jquery Selector for input value

You want to select the input, then take its parent div:

$("input[value='hello']").parent("div").css("background", "red");

Just as a future note to those that come across this question, these answers are correct for when searching for the specific value as an attribute i.e. the one hard-coded in the HTML — completely correct as per the question asked. However, if the value of the field is changed by the user at any point the value attribute is not updated, only the element's value property. This will lead to unexpected behaviour in the form of selecting elements that actually have different current values... instead — or at least until I find a better way — I've been using the following:

jQuery.extend(
  jQuery.expr[':'],
  {
    /// check that a field's value property has a particular value
    'field-value': function (el, indx, args) {
      var a, v = $(el).val();
      if ( (a = args[3]) ) {
        switch ( a.charAt(0) ) {
          /// begins with
          case '^':
            return v.substring(0,a.length-1) == a.substring(1,a.length);
          break;
          /// ends with
          case '$':
            return v.substr(v.length-a.length-1,v.length) == 
              a.substring(1,a.length);
          break;
          /// contains
          case '*': return v.indexOf(a.substring(1,a.length)) != -1; break;
          /// equals
          case '=': return v == a.substring(1,a.length); break;
          /// not equals
          case '!': return v != a.substring(1,a.length); break;
          /// equals
          default: return v == a; break;
        }
      }
      else {
        return !!v;
      }
    }
  }
);

The above creates a new jQuery pseudo selector, which can be used like so:

$('input:field-value(^test)');

Which will select all inputs that start with the value "test", or:

$('input:field-value(*test)');

Which will select all inputs that contains "test" anywhere in it's value.

Also supported are !<
