使用jQuery获取div中所有跨度的文本

Question

I'm dynamically adding span elements to a div. I want to retrieve the text from all the span elements in the div at a later stage. How do I do this? I'd like to use jQuery, but Javascript is fine I guess.

Section of Javascript creating the span elements:

var x = ui.item.value;

var span = document.createElement("span");
span.innerHTML="       "+x+"";

$("#selected").append(span);

This is inside an on click event. The div is called "selected".

Answer 1

You can try something like this:

 var txt= ""; $("#selected span").each(function(){ txt += $(this).text();//here you get the values from each span inside selected element }); $("body").append(txt);//here append the collected text inside eg body 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="selected"> <span>1</span> <span>1</span> <span>1</span> <span>1</span> </div> 

Answer 2

No need for a .each() or any other loop. Just calling .text() will be enough since, according to the JQuery docs , it:

Get the combined text contents of each element in the set of matched elements, including their descendants, or set the text contents of the matched elements.

So:

 $("#selected").click(function() { var text = $(this).find("span").text(); alert(text); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script> <div id="selected"> <span>1</span> <span>2</span> <span>3</span> </div>
