jQuery .search() to any string

Question

I saw this code snippet:

$(\"ul li\").text().search(new RegExp(\"sometext\", \"i\"));

and wanted to know if this can be extended to any str

Answer 1

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...
});

Answer 2

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));

Answer 3

if (str.toLowerCase().indexOf("yes") >= 0)

Or,

if (/yes/i.test(str))
