Getting a Jquery Selector for an Element

Get unique selector of element in Jquery

I'll answer this myself, because i found a solution which i had to modify. The following script is working and is based on a script of Blixt:

jQuery.fn.extend({
    getPath: function () {
        var path, node = this;
        while (node.length) {
            var realNode = node[0], name = realNode.name;
            if (!name) break;
            name = name.toLowerCase();

            var parent = node.parent();

            var sameTagSiblings = parent.children(name);
            if (sameTagSiblings.length > 1) { 
                var allSiblings = parent.children();
                var index = allSiblings.index(realNode) + 1;
                if (index > 1) {
                    name += ':nth-child(' + index + ')';
                }
            }

            path = name + (path ? '>' + path : '');
            node = parent;
        }

        return path;
    }
});

Getting a jQuery selector for an element

I see now that a plugin existed (with the same name I thought of too), but here's just some quick JavaScript I wrote. It takes no consideration to the ids or classes of elements – only the structure (and adds :eq(x) where a node name is ambiguous).

jQuery.fn.getPath = function () {
    if (this.length != 1) throw 'Requires one element.';

    var path, node = this;
    while (node.length) {
        var realNode = node[0], name = realNode.name;
        if (!name) break;
        name = name.toLowerCase();

        var parent = node.parent();

        var siblings = parent.children(name);
        if (siblings.length > 1) { 
            name += ':eq(' + siblings.index(realNode) + ')';
        }

        path = name + (path ? '>' + path : '');
        node = parent;
    }

    return path;
};

How to get this element using jQuery selectors?

I don't know why there are so many answers that you are using XPath because XPath was deprecated a long time ago and jQuery no longer supports it without the XPath compatibility plugin.

See Release Notes of 1.2 : http://www.learningjquery.com/2007/09/upgrading-to-jquery-12

XPath compatibility plugin : http://docs.jquery.com/Release:jQuery_1.2#XPath_Compatibility_Plugin

Just use $("#colorSwatchContent span") as your selector. Which is a css style seclector meaning find me all descendent span elements of an element with id colorSwatchContent. Since id's in html are unique identitfiers, this is about as specific as you can get.

$("#colorSwatchContent > span") will only select DIRECT descendents (immedieate children)

$("#colorSwatchContent > span:first") will select the first span direct descendent

Get the current jQuery selector string?

You can use selector property:

$('my_selector p').selector // my_selector p

version deprecated: 1.7, removed: 1.9

How to get a DOM Element from a jQuery selector?

You can access the raw DOM element with:

$("table").get(0);

or more simply:

$("table")[0];

There isn't actually a lot you need this for however (in my experience). Take your checkbox example:

$(":checkbox").click(function() {
  if ($(this).is(":checked")) {
    // do stuff
  }
});

is more "jquery'ish" and (imho) more concise. What if you wanted to number them?

$(":checkbox").each(function(i, elem) {
  $(elem).data("index", i);
});
$(":checkbox").click(function() {
  if ($(this).is(":checked") && $(this).data("index") == 0) {
    // do stuff
  }
});

Some of these features also help mask differences in browsers too. Some attributes can be different. The classic example is AJAX calls. To do this properly in raw Javascript has about 7 fallback cases for XmlHttpRequest.

Get Selector from a JQuery object

Oh, I see where your problem is. $(this) is not constructed using a selector, but rather by directly wrapping a DOM element, so it does not carry it anywhere. You can get the original selector obviously by doing $('.smartgridview-normal th').selector; but there's a big difference between $('.smartgridview-normal th') and $(this).

jQuery selector for id starts with specific text

Use jquery starts with attribute selector

$('[id^=editDialog]')

Alternative solution - 1 (highly recommended)

A cleaner solution is to add a common class to each of the divs & use

$('.commonClass').

But you can use the first one if html markup is not in your hands & cannot change it for some reason.

Alternative solution - 2 (not recommended if n is a large number)
(as per @Mihai Stancu's suggestion)

$('#editDialog-0, #editDialog-1, #editDialog-2,...,#editDialog-n')

Note: If there are 2 or 3 selectors and if the list doesn't change, this is probably a viable solution but it is not extensible because we have to update the selectors when there is a new ID in town.

jQuery: Get HTML including the selector?

In this specific case:

var outerHTML = $("<div />").append($('#example').clone()).html();

See this page for more details.

And the discussion here: http://api.jquery.com/html/ (this explains that this isn't in jQuery core and why some logical solutions won't work)

jQuery - selecting elements from inside a element

You can use any one these [starting from the fastest]

$("#moo") > $("#foo #moo") > $("div#foo span#moo") > $("#foo span") > $("#foo > #moo")
