regular expression in jQuery selectors

Question

I have the following HTML:

<div class="questionItem">
<input data-val="true" data-val-number="The field MappingId must be a number." 
       data-val-required="The MappingId field is required." 
      id="answers_2__MappingId" name="answers[2].MappingId" type="hidden" value="23" />
<input id="answers_2__Item" name="answers[2].Item" type="hidden" value="B0300" />
<input id="answers_2__SetAnswer" name="answers[2].SetAnswer" type="hidden" value="^" />
</div>

jQuery will get me all the questionItems with this:

var coll = $('.questionItem');

I don't need all of them, I simply need the questionItems that have a child input with a name of answers[/d+].SetAnswer and value of ?.

How does one construct that has() clause?

This may help: stackoverflow.com/questions/3086554/…

It should be something like this:

var coll = $(".questionItem").filter(function() {
    return $(this).find(":input").filter(function() {
        return /^answers\[\d+\]\.SetAnswer$/.test(this.name) && this.value == "?";
    }).length > 0;
});

Regular expressions aren't needed here. Just use :has and attribute selectors:

$(".questionItem:has(input[name$='.SetAnswer'][value='?'])");
