I was reading the documentation of the .on event handler of jQuery and I started playing around with it.
I have a simple <select> element with the multiple attribute set to true.
However, I want the user to be able to select multiple items without having to press the ctrl or shift key(s)
According to the .on documentation, if you specify a selector it will automatically add those event handlers to any new items added inside that container that match the selector specified.
So in my case, I could for example decide to replace the <option> elements available in the listbox, but I still want to have the same functionality for those options without having to rebind those events etc.
One might think that the following snippet should do the trick (atleast, I did):
$('#dropdownlist').on('mousedown', 'option', function(e){
e.preventDefault();
$(this).prop('selected', $(this).prop('selected') ? false : true);
return false;
});
So when a users clicks on an option in that listbox, the default action will be cancelled and depending wether the item is already selected or not, it will invert that selection.
I have created a small fiddle demonstrating this behaviour: fiddle
In that fiddle, the first dropdownlist is behaving as expected, but the functionality is lost when replacing the items. This only works in FF & Chrome.
The second dropdownlist is how I thought it should've been (event handling wise), but that doesn't seem to work besides in Chrome -.-
The functionality is kept when replacing items, because the console will still log '2' when clicking on an item after replacing them.
Can someone explain me why this is happening? Am I doing something wrong?
Please point me in the right direction!
Thanks!

IE doesn't respect the mousedown event on the option tag itself. You've got to use the OnChange event of the select tag, which is not what you (nor I) want. I was trying to do the exact same thing as you and was stopped at every attempt. I finally gave up and made it a list of checkboxes because I can get the same behavior out of mine that you are trying to do here.
You can see this question for some options, but I never did get it to work the way you are describing.

Problem:
By default in instantsearch.js, the reset button in the search field is hidden until you start typing. However the submit button doesn't hide, causing them to overlap, this seems default behavior(?)
Here is a demo that demonstrates the issue:
https://codesandbox.io/s/quizzical-leakey-7shzr
Expected Outcome:
I want the search submit button to replace (toggle) with the reset button on typing.
Things I've tried:
I have looked through the documentation and can't find any solution to this. There is a showReset and showSubmit parameters as seen here: https://www.algolia.com/doc/api-reference/widgets/search-box/js/ but these just disable them completely.
Changing the template for them in the widget, only stylizes them, rather than adjust their function.
I do have a heavy handed solution I've written in jquery below but my question is: Is there a way to configure this behavior in instantsearch.js?
$( ".ais-SearchBox-input" ).on("keyup", function() {
if($('.ais-SearchBox-input').val().length > 0){
$('.ais-SearchBox-submit').addClass('none');
}else{
$('.ais-SearchBox-submit').removeClass('none');
}
});
$(document).on('click', '.ais-SearchBox-reset', function() {
$('.ais-SearchBox-submit').removeClass('none');
});
The submit button is initially designed to be on the left hand side of the searchbox, and the reset one on the right hand side, as you can see in the InstantSearch.js SearchBox Storybook. In your demo, there's custom CSS that aligns them both on the right, which is why they're overlapping. But they're two orthogonal concepts, so they weren't designed to replace one another out of the box.
Your solution is fine, although I understand that having imperative logic like this on top of InstantSearch.js might feel icky. Another approach is to directly hook into the rendering logic of the widget by using the connectSearchBox connector. You'll be able to fully control what is rendered, and you'll have access to query which you'll be able to leverage to decide whether to show one button or the other.
My advice is to start from the full example and adapt it for your use case.
I am trying to Right click on an element and then select an option "Rename" from the list. I have got "right clicking" working but can't select option from the list. Referred links 1, 2
Note 1:
1: On right click the menu options that are visible are native context menus. So, they don't appear in my DOM that I can see.
2: The App runs only in Chrome browser(not sure if it is a browser issue)
I have tried the following code:
browser.actions().mouseMove(elementVar).perform();
browser.actions().click(protractor.Button.RIGHT).click(protractor.Button.ARROW_DOWN).click(protractor.Button.ARROW_DOWN).click(protractor.Button.ARROW_DOWN).perform();
Consider, "Rename" to be the third option in the list.
Note 2:
If I am just running the app and enter 'R' from my keyboard, it selects the "Rename" option. But when I tried to run it in my test, it doesn't select the "Rename" option. See below code I tried:
browser.actions().mouseMove(elementVar).perform();
browser.actions().click(protractor.Button.ARROW_RIGHT).sendKeys('R',protractor.Key.ENTER).perform();
None of the above code works. Let me know if more information is required.
EDIT:
I am guessing the following to be happening:
once I mouse over, the script "right clicks" and after that the "tooltip" is displayed. Since the "tooltip" is displayed after "right click" I think the menu list goes to the background(the list is still visible along with the tool-tip), which is why the arrow down keys aren't working. Is this possible? If yes, how can I wait for the tooltip to be invisible and then right click?
Input: I tried to wait for tool-tip to be invisible and then right click, but still the "Arrow_down" doesn't work.
Is there a way to bring the menu list in the front once we have right clicked?
IMPORTANT:
I took a screenshot after I right clicked on the element, and the screenshot doesn't show the "menu list". Below is the code for screenshot:
browser.actions().click(protractor.Button.RIGHT).perform()
.then(function() {
browser.takeScreenshot().then(function(screenShot) {
writeScreenShot(screenShot, "image.png");
});
});
//writeScreenShot takes two variables actual screenshot data and the file name. And the screenshot is saved as "image.png"
What needs to be done?
When you send ARROW keys to the browser, you have to send them as keys instead of passing them to click() function and the ARROW_DOWN key is part of Key object and not BUTTON. Here's how -
browser.actions().mouseMove(elementVar).perform();
browser.actions().click(protractor.Button.RIGHT).sendKeys(protractor.Key.ARROW_DOWN).sendKeys(protractor.Key.ARROW_DOWN).sendKeys(protractor.Key.ARROW_DOWN).perform();
For your second try, you should send RIGHT in the place of protractor.Button.ARROW_RIGHT to right click. When you send two actions/keys to sendKeys() function, you have to join them using chord object which combines the action of pressing two keys at a time(ex: CTRL+C for copy). But in your case i don't think its really necessary. Here's how to use it -
browser.actions().mouseMove(elementVar).perform();
browser.actions().click(protractor.Button.RIGHT).sendKeys(protractor.Key.chord("r", protractor.Key.ENTER).perform(); //Not necessary as you wont be pressing R+ENTER in your keyboard
OR
browser.actions().click(protractor.Button.RIGHT).sendKeys('R').sendKeys(protractor.Key.ENTER).perform();
Hope this helps.
use XPath to solve your problem
browser.actions().mouseMove(target).perform();
browser.actions().click(protractor.Button.RIGHT).perform();
element(by.xpath('//*[#id="context-menu"]/ul/li[1]')).click();
In your case it will be "//*[#id="context-menu"]/ul/li[3]" most probably.
On my homepage I have a form with a search textbox. If you click on the input and start typing when the page in still loading, something steals the focus so you have to click back in the input textbox.
Is there a way to prevent this from happening? Do I need to find what is stealing the focus?
Sounds like one of your scripts is setting something to focus on load.
Put this at the bottom of your HTML right before </body>. Your console will show you the HTML of the item that is gaining focus.
<script>
$(window).load(function() { // NB not document ready
console.log($(':focus')[0]);
// alert($(':focus')[0]); // if you don't know what console is
});
</script>
Hopefully there will be an ID in the element that you can search your script for, or enough clues to let you find what's being told to focus on load. Then you can remove/alter that line.
Addendum
It turns out this is the culprit
$('#f input#livesearch').clearableTextField();
That clearable function is only ever going to be required if the user uses that field, so let's make it contextual, i.e. only when it's given focus, make that function available. This should stop the naughty plugin stealing focus.
$('#f input#livesearch').on('focus', function(){
$(this).clearableTextField();
});
It's generally best to write contextually - you'll find pages with dozens of binds and "live" events being set up on onload, but they are rarely used. If it's something that doesn't need to happen until the user does something or until you can tell a user is about to do something, write it that way.
The object is to Show-Hide text located under their respective Titles, so a User reads the title and shows or hides text belonging to that title if the User wants to read more.
I tried whatever I could find so far on here, we're talking dynamically setting text coming from a spreadsheet, can't use IDs, must work with .class, must be missing something, I have this piece of code:
... html.push('<div class="comments">' + comment + '</div></div></div>');
but when I try this Show-Hide code nothing happens, even if the error console shows nothing. Basically I want to Show-Hide the .comments class divs with a show-hide toggle link located under each of them. I say them because the .comments divs are reproduced dynamically while extracting text coming from Google spreadsheet cells/row (one .comments div per spreadsheet row). I tried .next, child and parent but they all divorced me so I dunno looks like a dynamic issue. So far I only managed to globally toggle all divs to a visible or hidden state but I need to toggle independantly individual divs.
I prefer a jQuery solution but whatever worked so far was achieved with native javascript.
Note: If a cross-browser truncate function which would append a more-less link after a number of words (var) in each .comments divs would be easier to implement then I would gladly take that option. Thx for any help, remember I am still learning lol!
I have been working on an entirely JS UI project and have brought myself to using $('', { properties }).appendTo(BaseElement) to work best for adding HTML elements because it appropriately manipulates the DOM every time.
If you are having good luck with push elsewhere, however, breakpointing on the line where you do your $('.class').hide() and see what $('.class').length is. Alternately, you can just add alert($('.class').length) to your code if you are unable to breakpoint the code. If it is 0, then your elements have not been properly added to the DOM. Changing to append will ensure they are part of the DOM and therefore targetable via JQuery.
I have an Ext Js panel that I am adding to my main TabPanel. The panel I am adding contains a FormPanel as one of it's items and inside the FormPanel I have a Name field. What I want to do is change the name of the Tab based on the name in the form field.
The problem is that if I call the FormPanel's getForm().getValues() inside of the panel's initComponent, I get the following javascript error:
Uncaught TypeError: Cannot read property 'dom' of undefined
If I do this outside of initComponent (e.g. on a button press) everything works fine. After doing some testing, I think the issue is that the FormPanel isn't actually rendered yet (and thus the dom doesn't exist), getValues() fails. However, I can't seem to figure out a way to get my FormPanel's values from the Panel on load.
I tried to listen for events. I tried:
this.detailForm.on('afterrender', function () { alert('test'); });
but doing this showed that AfterRender is called prior to the form actually being rendered (it's not visible on the screen). Changing the alert to my custom function handler produces the previous dom exception. I attempted to use the activate and enable events instead of afterrender, but even though the API says that FormPanel fires those events, the alert('test') never gets called.
I can't seem to find any way for my panel to get the inner FormPanel's values upon loading my panel. Does anyone have any ideas?
Using getFieldValues() in place of getValues() will collect values by calling each field instance's getValue() method instead of by reading from the DOM. This should allow you to get your values regardless of the form's rendered state.
I've got the same problems on one of my projects, I managed to fix it using the afterlayout event.
I'd give setting .deferredRender:false a try.
Ext.TabPanel.deferredRender
Probably best to roll out of your afterlayout changes, then test with just a straight deferredRender:false config item.
I believe the problem is caused because the inactive tabs are not rendered until they become active. In your scenario, you cannot get the values, because they don't exist until the tab is activated/shown.
Setting deferredRender:false will render the items within all tabs. There could be a performance hit by setting deferredRender:false, so testing you must do.
Hope this helps.
