Question

How can you use the :contain() on an input field, e.g.

#inputfield contains a dynamic value of 5.938 and I want to use $("#inputfield:contains('5.938')").

But that won’t work, I’ve provided a demo at jsFiddle.

I don’t want to use if(element.val() == '5.938') because I need a provisional selector instead doing an if/else statement.

I also don’t mean by using [value=5.938] because the value will change.

Due to @Neal’s answer, you need to use some sort of conditional. A simple selector won’t work. .filter() will suffice, however:

$('#inputfield').filter(function ()
{
    return $(this).val() == '5.938';
});

That said, it looks like you’re using an ID selector, which can select at most one element, so .filter() is overkill — if...else really makes the most sense in that case.
