jQuery selector for an element that directly contains text?

Question

I was able to get this partially working using the :contains selector, but my problem is if an element contains an element that contains the text it is still returned. For example:

$('div:contains("test")')

Will select both divs below:

<div>something else
   <div>test</div>
</div>

How can I select only divs that "directly" contain the text? Meaning that in the above example only the child div would be selected.

UPDATE:

Just to clarify, if I were searching for the text "something else" instead of "test" then I would like to only find the parent div.

$('div>:contains("test")') is not a general solution, it only works for your specific example. It still matches any element whose descendants contain the text test, as long as its parent is a div.

There is in fact currently no selector that will select only direct parents of text nodes containing your target text. To do it you would have to walk the DOM tree yourself checking each text node you find for the target text, or write a plugin to do the same. It'd be slow, but then not as slow as :contains already is (it's not a standard CSS selector so you don't get browser-native fast selector support).

Here's a plain DOM function you could use as a starting point. It might be improved to find text in adjacent (non-normalised) text nodes, or to hide it in a plugin/selector-extension.

function findElementsDirectlyContainingText(ancestor, text) {
    var elements= [];
    walk(ancestor);
    return elements;

    function walk(element) {
        var n= element.childNodes.length;
        for (var i= 0; i<n; i++) {
            var child= element.childNodes[i];
            if (child.nodeType===3 && child.data.indexOf(text)!==-1) {
                elements.push(element);
                break;
            }
        }
        for (var i= 0; i<n; i++) {
            var child= element.childNodes[i];
            if (child.nodeType===1)
                walk(child);
        }
    }
}

Just to complete the knowledge base. If you need to get all DOM elements within the body (not only DIVs) that contain specific text or characters you can use:

function getNodesThatContain(text) {
    var textNodes = $(document).find(":not(iframe, script)")
      .contents().filter( 
          function() {
           return this.nodeType == 3 
             && this.textContent.indexOf(text) > -1;
    });
    return textNodes.parent();
};

console.log(getNodesThatContain("test"));

Hope that helps.

You might have to do an in-efficient query. Do not use this solution if someone finds a selector that manages to filter out child elements: http://viralpatel.net/blogs/2011/02/jquery-get-text-element-without-child-element.html

$("div:contains('test')")
    .clone()    //clone the element
    .children() //select all the children
    .remove()   //remove all the children
    .end()  //again go back to selected element
    .filter(":contains('test')")

edit: that snippet above is just to test the element, in implementation it would look more like this: http://jsfiddle.net/rkw79/TT7dR/6/

$("div:contains('test')").filter(function() {
    return (
    $(this).clone() //clone the element
    .children() //select all the children
    .remove() //remove all the children
    .end() //again go back to selected element
    .filter(":contains('test')").length > 0)
}).css('border', 'solid 1px black');

try adding the greater than:

$('div>:contains("test")')
