如何使用jQuery选择文本区域内的所有URL？

Question

I can select all img link as well as PDF link using the following:

    $("a[href$='pdf']").append('<img src="pdf.jpg" style="width:20px;height:20px;" > ');
    $("a[href$='jpg']").append('<img src="jpg.jpg" style="width:20px;height:20px;" > ');

Now I have a text area

 <textarea id="mytxt" name='post' style='width:100%;height:400px;margin-top:10px;border:solid thin #F1F1F1;line-height:20px;'>

  </textarea>


 $("#mytxt:contains('.jpg')").append('<img src="jpg.jpg" style="width:20px;height:20px;" > ');

The above selector won't work.

Answer 1

you cannot append a DOM element inside a textarea, so the above code can't work

the selector itself $("#mytxt:contains('.jpg')") is perfectly working when a .jpg occurence is found : see fiddle http://jsfiddle.net/Mqu66/
