Question

I am selecting a list of table rows within my document.

The following code selects:

1. All table rows…
2. That contain a DIV with class .val-string
3. With a child input that holds the value “null”.

$('tr').children('.val-string').children('input'):not([value!=null])').each(function(k,v) { });

This works for selecting those inputs that contain the value “null”, but I also want it to work with “Null”, “NULL” or even “nUlL”.

I have tried using:

... children('input'):not([value.toLowerCase()!=null])') ...

amongst other variations/placements of the toLowerCase() function.

Basically, can what I ask for be performed in one line of code like the one I’m trying to execute above?

This link seems to suggest using a modified :contains function, but I don’t want to change this function for all my code as it is used elsewhere and requires case sensitivity.

Answer 1

there is no selector for or but you can use filter

$('tr .val-string input').filter(function(){  
    return this.value.toLowerCase() =='null';
}).doSomething();
