如何获取包含Javascript / Jquery中单击文本的元素？

Question

I would like to replace the text on pages when I click on the text or even just replace the single word clicked on. I have tried a top down approach selecting all elements in the DOM, filtering out the textNodes, wrapping each with tags and adding a click event handler to each tag. But this is far too slow and inefficient particularly on very large and dynamic sites.

I only need to replace the text that was clicked. Is there a bottom up way of doing this starting from the event.target? How do I find the closest textNode to the event.target, for example?

Answer 1

In the example you gave, you can just do the following; for more info see How do I select text nodes with jQuery?

$(document).click(function(event) {     
    textNodes = $(event.target).contents().filter(function() {
        return this.nodeType == 3;
    });

    textNodes.each( function() {
         $(this).replaceWith("New Text");
    });
})

Answer 2

Have you tried Jquery's .closest() ?

Description: For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.
