Return all elements for which any attribute begins with something

Question

I know [name^="value"] selector , but is there a similar selector (or method) that asks for all attributes starting from the given value?

I am looking for something like $("[*^='http://www.something.com']")(this does not exist).

It will match all elements containing at least one attribute with a value starting with http://www.something.com.

Say:

<img src="http://www.something.com/image.jpg" />
<a href="http://www.something.com">Something</a>
<link rel="stylesheet" href="http://www.something.com/css/style.css" type="text/css">

The attribute name can be anything, not just, srcand hrefeven non-standard attributes.

Is there a known way to do this?

Answer 1

I gathered some ideas from other answers and wrote my own selector.

selector

$.expr[':'].hasAttrStartingWithValue = function (obj, index, meta) {

    var startsWithAttrValue = false;
    var value = meta[3];

    for (var i = 0; i < obj.attributes.length; i++) {
        var attr = obj.attributes[i];
        // attr.value starts with value
        if (attr.specified && attr.value.lastIndexOf(value, 0) === 0) {
            startsWithAttrValue = true;
            break;
        }
    }

    return startsWithAttrValue;
};

, , , , , IE 11, FF 24 Chrome 32.

// Logs every occurrence of a value in any attribute of the page
$(":hasAttrStartingWithValue('http://www.something.com')").each(function (i, e) {
    console.log(i + " - " + e.outerHTML);
});

// Matches only children of test
$("#test :hasAttrStartingWithValue('http://www.something.com')")
   .css('background-color', 'red');

function strstr (haystack, needle, bool) {
  var pos = 0;

  haystack += '';
  pos = haystack.indexOf(needle);
  if (pos == -1) {
    return false;
  } else {
    if (bool) {
      return haystack.substr(0, pos);
    } else {
      return haystack.slice(pos);
    }
  }
}
    $( document ).ready(function(){
    $('*').each(function() {
      $.each(this.attributes, function() {
        // this.attributes is not a plain object, but an array
        // of attribute nodes, which contain both the name and value
        if(this.specified) {
          if( strstr(this.value,'http://') )
            alert(this.name+'+'+this.value);
        }
      });
    });

    });
