I saw this code snippet:
$("ul li").text().search(new RegExp("sometext", "i"));
and wanted to know if this can be extended to any string?
I want to accomplish the following, but it dosen't work:
$("li").attr("title").search(new RegExp("sometext", "i"));
Also, anyone have a link to the jQuery documentation for this function? I fail at googling apparently.
This question is related to

search() is a String method.
You are executing the attr function on every <li> element.
You need to invoke each and use the this reference within.
Example:
$('li').each(function() {
var isFound = $(this).attr('title').search(/string/i);
//do something based on isFound...
});
Ah, that would be because RegExp is not jQuery. :)
Try this page. jQuery.attr doesn't return a String so that would certainly cause in this regard. Fortunately I believe you can just use .text() to return the String representation.
Something like:
$("li").val("title").search(/sometext/i));
if (str.toLowerCase().indexOf("yes") >= 0)
Or,
if (/yes/i.test(str))
