target input by type and name (selector)

I need to change some checkbox inputs to hidden inputs for some but not all inputs on a page.

<input type="checkbox" name="ProductCode"value="396P4"> 
<input type="checkbox" name="ProductCode"value="401P4"> 
<input type="checkbox" name="ProductCode"value="F460129">

The jquery code below only selects the input by type which causes all check boxes to changed to hidden inputs Is there a way to check for both type of input="checkbox" and name="ProductCode" as the selector so I can specifically target those that I want to change?

$("input[type='checkbox']").each(function(){
var name = $(this).attr('name'); // grab name of original
var value = $(this).attr('value'); // grab value of original
var html = '<input type="hidden" name="'+name+'" value="'+value+'" />';
$(this).after(html).remove(); // add new, then remove original input
});

Solution 1:

You want a multiple attribute selector

$("input[type='checkbox'][name='ProductCode']").each(function(){ ...

or

$("input:checkbox[name='ProductCode']").each(function(){ ...

It would be better to use a CSS class to identify those that you want to select however as a lot of the modern browsers implement the document.getElementsByClassName method which will be used to select elements and be much faster than selecting by the name attribute

Solution 2:

You can combine attribute selectors this way:

$("[attr1=val][attr2=val]")...

so that an element has to satisfy both conditions. Of course you can use this for more than two. Also, don't do [type=checkbox]. jQuery has a selector for that, namely :checkbox so the end result is:

$("input:checkbox[name=ProductCode]")...

Attribute selectors are slow however so the recommended approach is to use ID and class selectors where possible. You could change your markup to:

<input type="checkbox" class="ProductCode" name="ProductCode"value="396P4"> 
<input type="checkbox" class="ProductCode" name="ProductCode"value="401P4"> 
<input type="checkbox" class="ProductCode" name="ProductCode"value="F460129">

allowing you to use the much faster selector of:

$("input.ProductCode")...

Solution 3:

input[type='checkbox', name='ProductCode']

That's the CSS way and I'm almost sure it will work in jQuery.
