I have a div called album_number_xx (xx being digits).
this div contains another set of divs, each one representing an image with caption and other details.
I need to allow the user to reorder images by drag and drop, and then update the database with the new order.
using jQuery sortable and serialize, I'm able to get the sequence of images on update. But don't know how to get the album_id, (the xx in the name of the container div).
I though that maybe I can grab the name of that div, store it in variable and then cut the last digits, but don't know how to do it.
any ideas?
thanks,
Patrick
I don't know how you're grabbing the div name, but if you have it in a variable:
var albumId = divNameVariable.split('_')[2];
var name = $('div[id^=album_number]').attr('id');
var num = parseInt(name.substr(name.lastIndexOf('_') + 1));
Based on Scott Evernden answer you can do it on click event:
$(document).ready
(function()
{
var albums = $("div[id^='album_number']").click
(function()
{
var id = $(this).attr('id');
var numberId = id.substr(id.lastIndexOf('_') +1);
alert(numberId);
});
});

I am trying to get marker's .bindPopup content on click event so I can save it to localStorage. But it is not working properly for each marker.
L.marker([76.920614, -60.117188])
.addTo(map)
.bindPopup('<div><span class="claimed">DATA 1</span></div>')
.on('click', groupClick);
L.marker([77.841848, -31.289063])
.addTo(map)
.bindPopup('<div><span class="claimed">DATA 2/span></div>')
.on('click', groupClick)
function groupClick(event) {
var a = document.querySelector('.claimed').innerHTML;
console.log(a);
}
it would work on first click but on the second click on different marker, it will take the data from the first marker that i clicked instead of the second marker. In this case i have to click somewhere else on the map or click the popup close button first before i can click on the next marker to properly get the data. is there any fix on this?
PROBLEM:
you are selecting in your function only the first appearance of the class (not the clicked ones child) at
var a = document.querySelector('.claimed').innerHTML;
SOLUTION 1 (NOT RECOMMENDED):
You should use the this keyword, and the getPopup() and getContent() methods instead, your function should look something like:
function groupClick(event) {
var a = this.getPopup().getContent();
console.log(a);
}
This way you'll get the escaped html, so a much better and proper way is...
SOLUTION 2 (RECOMMENDED): if you store the necessary data in the markers options (instead of storing and getting html from popup), like this:
L.marker([40, 12], {data: 1, datastring: 'first'})
.addTo(map)
.bindPopup('ONE')
.on('click', groupClick);
Then you can access this options in your function this way:
function groupClick(event) {
var a = this.options.data + ' ' + this.options.datastring;
alert(a);
}
A working fiddle again.
EDIT: I have found a workaround for the desired logic. But still, you need to link the marker and its popup content, because:
Popup content is not a node in the DOM, so you cannot access it before it is opened with a user click.
So in my solution i store a simple integer in the marker options (divId: int), which is the unique id of the marker. In the popup content, the radio inputs have the same id concatenated with the desired string (<input type="radio" id="Item-10-0" name="Item-10" value="0" checked="">).
L.marker([40, 32], {
divId: 10
})
.addTo(map)
.bindPopup('<div id="2div" class="popup-todo"><input type="radio" id="Item-10-0" name="Item-10" value="0" checked=""><label for="Item-10-0">Claimed</label><input type="radio" id="Item-10-1" name="Item-10" value="1"><label for="Item-10-1">Unclaimed</label></div>')
.on('click', groupClick);
If the user clicks, the new node is already accessible, so you can select it and use its id and value.
function groupClick(event) {
var a = document.querySelector('input[name=Item-'+this.options.divId+']');
document.querySelector('#demo').innerHTML = a.id + ' ' + a.value;
}

I need to manipulate the text elements of the first and last tick of an axis to bring them more towards the center.
I am trying to select them, one at the time, with something like svg.select('.tick:last-child text') but it doesn't work. I'd then apply .transform('translate(4,0)')...
Am I doing something wrong? How can I achieve this?
One thing you could do is to create custom sub-selections by adding methods to d3.selection.prototype. You could create a selection.first() method that selects the first item in a selection, and a selection.last() method that selects the last item. For instance:
d3.selection.prototype.first = function() {
return d3.select(this[0][0]);
};
d3.selection.prototype.last = function() {
var last = this.size() - 1;
return d3.select(this[0][last]);
};
This would let you do the following:
var tickLabels = svg.selectAll('.tick text');
tickLabels.first()
.attr('transform','translate(4,0)');
tickLabels.last()
.attr('transform','translate(-4,0)');
Of course, you need to make sure that you only have one axis if you do it that way. Otherwise, specify the axis in your initial selection:
var tickLabels = svg.selectAll('.axis.x .tick text');
HERE is an example.
Here's the cleanest method I've found:
g.selectAll(".tick:first-of-type text").remove();
g.selectAll(".tick:last-of-type text").remove();
As google brought me here, I also want to add a cleaner method to what Adam Grey wrote.
Sometimes you just want to do it without taking a reference of selectAll .
svg.selectAll('.gridlines').filter(function(d, i,list) {
return i === list.length - 1;
}).attr('display', 'none');
the 3rd parameter of the filter function gives you the selected List of elements.
They don't exist in d3 specifically, but you can use the .firstChild and .lastChild methods on a node.
You can first select all of the parents of the node, and then operate within the scope of a .each() method, like so:
d3.selectAll('.myParentElements').each(function(d,i){
var firstChild = this.firstChild,
lastChild = this.lastChild;
//Do stuff with first and last child
});
Within the scope of .each(), this refers to the individual node, which is not wrapped by a d3 selection, so all of the standard methods on a node are available.
Using .filter() with a function also works selection.filter(filter) :
var gridlines;
gridlines = svg.selectAll('.gridlines');
gridlines.filter(function(d, i) {
return i === gridlines.size() - 1;
}).attr('display', 'none');
It's for D3.js v4
d3.selection.prototype.first = function() {
return d3.select(
this.nodes()[0]
);
};
d3.selection.prototype.last = function() {
return d3.select(
this.nodes()[this.size() - 1]
);
};
Example:
var lines = svg.selectAll('line');
lines.first()
.attr('transform','translate(4,0)');
lines.last()
.attr('transform','translate(-4,0)');
Here is another, even though I used Fered's solution for a problem I met.
d3.select(d3.selectAll('*').nodes().reverse()[0])
For example, I am randomly picking a button element from within the rows of a table.
After the button is found, I want to retrieve the table's row which contains a selected button.
Heres is my code snippet:
browser.findElements(by.css('[ng-click*=submit]')).then(function (results) {
var randomNum = Math.floor(Math.random() * results.length);
var row = results[randomNum];
// ^ Here I want to get the parent of my random button
});
As of the most recent Protractor (1.6.1 as of this writing), the syntax changed a bit:
var row = results[randomNum].element(by.xpath('..'));
(use element() instead of findElement()).
Decided to use xpath.
var row = results[randomNum].findElement(by.xpath('ancestor::tr'));
You can now use
var element = element(by.css('.foo')).getWebElement()
var parentElement = element.getDriver() // gets the parent element
to get the parent element. See http://www.protractortest.org/#/api?view=webdriver.WebElement.prototype.getDriver for more info.
Actually, at the moment there is an easier way to select the parent of an element avoiding to use xpath.
From an ElementFinder you can simply access the parent element through parentElementArrayFinder and for example then trigger directly the click method:
myElement.parentElementArrayFinder.click();
I am new to dashcode and trying to build a simple web app for iphone using it. My primary aim is to have a Rectangular List (I have used the "Rounded rectangle list"). It is a static list and has three rows. What I want is a website to open when user clicks on any of the row, and each row would have a different URL. I was able to add a Rounded rectangle list with three static rows like
The object ID is "list"
Row 1-- Label- "Gift Cards" , Value - "http://www.abcxyz.com/giftcard"
Row 2-- Label- "Toys" , Value - "http://www.abcxyz.com/toys"
Row 3-- Label- "Bikes" , Value - "http://www.abcxyz.com/bikes"
i added onclick even to call a java script function like below
function myButtonPressHandler(event)
{
var websiteURL = "http://www.abcxyz.com/giftcard";
location = websiteURL;
}
the above code opens the same URL "http://www.abcxyz.com/giftcard" when the user clicks on any of the three buttons, but what I want is to fetch the value of each child node (which would be their respective URLs) at runtime and open it using location = WebsiteURL something like below (did'nt work for me :( -
function myButtonPressHandler(event)
{
var websiteURL = document.getElementById("list").children;
var WebURL = websiteURL[???].value;
location = WebURL;
}
Any help would be appreciated.
Thanks
OK ... so figured out my own answer. The Rounded Rectangular list is actually a multidimensional array. so to get the value of each of the rows i.e. the Http URLs and open them on the browser when the rows were touched/tapped/pressed is as below.
function buttonpresshandler(event)
{
// Insert Code Here
var list = document.getElementById("list").object;
var selectedObjects = list.selectedObjects();
//Open webpage with the value of each label
location = selectedObjects[0][1];
}
Hurray!
After dojo drag and drop, once the page is submitted, I have to save the position of every item that has been placed into "targetZone". How can we save the position?
Eugen answered it here :
Dojo Drag and drop: how to retrieve order of items?
That would be the right way. If you look at the link above, you can save the resulting "orderedDataItems" object as a JSON ...
Look at the following function. It saves our DND "Lightbox" (dojo.dnd.source) to a JSON.
_it is the current raw dnd item
_it.data.item contains all your stuff you need to keep
in our case _it.data.item.label keeps the customized nodes (pictures, video, docs) as a string, we can use later to dojo.place it
it is the dnd item you want to save without dom nodes
E.g. if you drop items from a dijit tree to a arbitrary dojo dnd source / target:
_RAM or _S in our data.item we made before needs to be overwritten.
LBtoJson: function(){
var that = this;
var orderedLBitems = this.dndSource.getAllNodes().map(function(node){
var _it = that.dndSource.getItem(node.id);
var it = { data:{ item:{} }, label:'', type:'' };
if((_it.data.item._RAM)){_it.data.item._RAM={}}
if((_it.data.item._S)){_it.data.item._S={}}
it.data.item = dojo.clone(_it.data.item);
it.label = it.data.item.label[0]||it.data.item.label;
it.type = _it.type;
console.log( it );
return it;
});
var LBjson = dojo.toJson(orderedLBitems);
return LBjson;
}
By calling getAllNodes(), you'll receive a list of nodes in the order they are shown. So if you wanted to save a list in a specific order, you could do something similar to this:
var data;
var nodes = dndSrc.getAllNodes();
for(var i; i < nodes.length; i++)
{
data.push({id: nodes[i].id, order: i});
}
