I'm trying to implement a live search combo. It suppose to work like this:
When I enter a character into the combo field I read the current value and send it as a parameter to the store's url. In the backend the parameter is used to return any value from the database that contains it, so the store behind the combo gets filled only with those filtered values.
As I continue to enter characters into the combo, the parameter should be updated and sent again to the backend and so on, getting like this a smaller and smaller store.
I tryied to achieve this behaviour using the combo's event keypress, even keyup, but the problem is it's impossible for me to get access to the current value from the combo field.
For example, when I entered the "for" string into the combo, how can I obtain this value using the combo object? comboName.getValue() doesn't work, it returns nothing "".
I already saw the live combo example here: http://docs.sencha.com/extjs/4.2.2/#!/example/form/forum-search.html but doesnt help me at all.
So my big question is: how do i get the current value while still editing the combo's field?
Any help would be appreciated, thanks.
You should be able to use
comboName.getValue();
or
comboName.getRawValue();
Where comboName is your combo box. Are neither working- I note in your post you state getValues() which is an improper method. You may want to also check whether when you're referring to your combo box object, that the reference is actually correct. The first argument from the key events is actually the object itself, so you should be able to do, e.g.
listeners:{
keyup:function(comboBox){
var value = comboBox.getValue() || comboBox.getRawValue();
console.log(value);
}
}
Swapping you the value getting method as appropriate.
I found that the combo already has a quick search behaviour, I just have to set queryMode on 'remote' and some other small configurations. More details here:

I have an app with some input fields that I'm trying to automate. The gist of these fields is that I should be able to double click a field, type in a new value, then press Enter to submit that value, which sends a PUT request and also closes the input field. This works for any input type except date.
So far I've tried:
Using cy.type('{enter}'). This gives Typing into a date input with cy.type() requires a valid date in the format 'yyyy-MM-dd'. You passed: {enter}
Using cy.trigger() to send out a keydown event for the enter key. This works, as in it closes the input field successfully but it somehow doesn't send the PUT request.
Pressing enter on the parent Element. Same as using cy.trigger()
Strangely enough, manually opening the input field myself, typing a date and pressing enter will send the request just fine. It seems to me like there's some issue with programmatically pressing enter to submit the field without Cypress interpreting this as my attempt to actually type an invalid character into the date field. The docs do specifically say that no special characters are allowed in a date field.
Can't post any code as this is corporate.
I have tried to let it work, but it simply can't be done at the moment. Something like this should work:
it.only('test', function () {
cy.visit('https://www.html5tutorial.info/html5-date.php')
cy.get('input')
.type('2009-12-12')
.type('{enter}')
})
But it doesn't so I started to dig into the pile of issues and found this one:
https://github.com/cypress-io/cypress/issues/3405 . It is about a different input type, but I believe it is related to your problem.
Unfortunately this problem is still present in Cypress 9.5. One possible work-around is to directly trigger the Javascript keyup or keydown event that you are listening for.
cy.get('input')
.type('2020-01-01T12:00')
.trigger('keydown', {
key: 'Enter',
});
This works for me, but as you pointed out might not in all situations. It depends entirely on how your app is listening for Enter in the first place and on which element.
Another possible option is to call .submit() on the form that wraps the input. If you're testing a component, you could create your own wrapper component that contains a form in order to trigger the submit.
You should remove 'date' attribute like below:
cy.get('input').invoke('removeAttr','type').type('2009-12-12{enter}');
I used something like that in my code, and it worked properly
cy.get('get-your-input').invoke('removeAttr', 'type')type('2022-12-01{enter}').trigger('change');
cy.get('get-your-input').invoke('attr', 'value', '2022-12-01').trigger('change');
cy.get('get-your-input').invoke('attr', 'type', 'date');
Please add date plus enter keystroke in the type: cy.get("#date").type("02-02-2022{enter}");
I wish to create a VSCode extension with an entry form on it - some way of input. So far I have only seen document processing or output for an extension.
How can you display a form of input fields in a vscode extension?
How much data do they need to enter? If it's not much, you should be able to handle it with a series of InputBoxes
From https://code.visualstudio.com/docs/extensionAPI/vscode-api
showInputBox(options?: InputBoxOptions): Thenable<string>
Opens an input box to ask the user for input.
The returned value will be undefined if the input box was canceled (e.g. pressing ESC). Otherwise the returned value will be the string typed by the user or an empty string if the user did not type anything but dismissed the input box with OK.
Parameter Description
options?: InputBoxOptions
Configures the behavior of the input box.
Returns Description
Thenable<string>
A promise that resolves to a string the user provided or to undefined in case of dismissal.
The Visual Studio Code API does not have any native methods to display forms to collect input. You can however, chain together Input Boxes, Quick Picks, etc... You can find all these methods under vscode.window.(...).
If these do not satisfy your needs you can implement a webview which allows you to render integrated HTML in Visual Studio Code and trade messages with the extension.
The most simple aproach would be to simple send all collected data from the form to the extension once you hit the submit button or something similar.
You have a nice little tutorial on how to do that here.
Another approach is to see how far you can go with editing JSON objects in settings.json. I thought I would need a form for 8-10 fields, but it turns out that I can create a settings template that has a series of labels and and entry fields (with type validation).
I'm creating a multilingual Drupal site and trying to implement a search function, that only displays results in the current language, that the user is viewing the site through.
Using Drupals own searchfunction at /search/node it is possible to select which language to search for through the "Advanced search" options, and it works perfectly. However, I dont want to expose these language selectboxes, I just want it to only search in the current language automatically.
What's the best option to do this?
I have one solution where I create a hook_form_alter function, that sets the #default_value in the language selectboxes to the current language, and then I hide the whole "advanced options" with in css. This doesnt seem very right though.
I think the most clean solution would be to hook into Drupals form-processing process and append ex "language:en" to the input text, but I cannot get this to work.
Does anyone know if it is possible via one of the Drupal form related alter functions, to get a hold of the input text and alter it before drupal does its final processing of it?
To answer your question specifically, while using 'hook_form_alter', you have a referenced variable called '$form_state'. This stores the values in the form, and any change there will be passed further.
Also,
I think setting a default value and hiding the field is a good solution as any, only, if you are hiding it you should do it server side, while altering the form. The same field you are setting the default value to. like this:
$fieldname['#type'] = 'hidden'.
I am stumped beyond belief.
I have a select box being generated by the cakephp form helper. I am feeding it an array of options, and passing an empty value... pretty standard stuff.
However, my "empty" field is showing up at the very bottom of the list.. not the top. So when the field loads, it just defaults to the first option... which is not the "empty" option.
Not a whole lot of room for error on the code here..
echo $this->Form->input('whatever',array('empty'=>'Choose One','options'=>$categories));
The only small item that might be important, is that $categories is a multi-array, so the select box has optgroups & options.
Is there some quirk/bug out there that I do not know of that is trying to force me to sneak into my scotch supply a few hours ahead of schedule?
edit: using the latest release of cakephp 1.3.x
I think that I once had the same problem.
It turned out to be the data (options array).
Is there an option with an empty key? probably the last one then.
this lead to the scenario I remember and seems to be the exact same thing.
the form helper will override this empty key value pair then and not create a second one.
without more infos from your end this will be difficult to solve.
OK, let's start with the Html.Textbox. It is supposed to contain text read from a file. The file read is based on what the user picks from a dropdown list.
The first time it is fine. The user picks a value from the dropdown list. The controller uses that value to read some text from a file, and returns that text to the view via the view model. Everything is fine.
THen the user picks another value from the dropdown list. The controller reads a new value from a file and returns it via the view model. Debugging to the LINE BEFORE THE HTML.TEXTBOX is set in the view shows that the model contains the correct value. However, the textbox itself still shows the PREVIOUS value when the page displays!
If I switch from Html.Textbox to a plain input, type="text" html control, everything works fine. That's not so hard, but the same thing happens with my dropdown list -- I can't set the selected value in code. It always reverts to whatever was chosen last. Rendering a "select" tag with a dynamically-generated option list is a pain. I would love to be able to use Html.Dropdown.
What am I missing here?? This is such a simple thing in webforms!
When you post a form, the values that are posted are put into ModelState. When the HtmlHelper renders an html iunput element, e.g. Html.TextBoxFor(x => x.FirstName), it'll search various locations to get the value for the textbox... ModelState is before ViewData.Model in the list of locations. So there for, the previously posted value will appear in your textbox.
To fix this you could clear the ModelState value or update the ModelState value. BUT I would kinda view that as a hacky way of getting around the problem.
The real issue has more to do with the flow of the posts and requests. I would personally look into that and maybe implement the PRG (Post Redirect Get) pattern.
HTHs,

Following on from what Charles/Charlino said:
Model binding updates the ModelState object, which contains validation and model binding errors that are collected during model binding.
Inside an action method, model binding has occurred already to update the model, and generated the ModelState object. If you now update the value on the model inside the action, you must also manually update the model state (since the helpers use it to generate their HTML). Below is an example:
model.CaptchaIsValid = CaptchaService.ValidateAndExpireCaptcha(model.CaptchaAttempt);
if (!model.CaptchaIsValid)
{
ModelState.AddModelError("CaptchaAttempt", "Incorrect - please try again");
}
// I'll clear the value on each attempt, to force them to re-enter a CAPTCHA.
model.CaptchaAttempt = string.Empty;
// Since I updated the model, I must create a new ValueProvider result...
ValueProviderResult clearedValue = new ValueProviderResult(
model.CaptchaAttempt,
model.CaptchaAttempt,
CultureInfo.CurrentCulture);
// ... and update the ModelState's value.
ModelState.SetModelValue("CaptchaAttempt", clearedValue);
The biggest issue I see here is that you are trying to do a postback within MVC. That model is really not supported, and is actually way more trouble than it is worth (as it seems you are finding out). I would recommend using Ajax to update the contents of the dropdown dynamically.
