纯JavaScript中的jQuery属性“ [something * = something]”选择器

Question

I am curious if pure javascript can replace this jQuery selector for IE7 and greater..

Do people simply change the markup and select using a class or is their away of selecting this using pure javascript

<h1 rel="xxxexternalxxx">Attribute Contains</h1>

var arrinput = $('[rel*="external"])

Any help would be much appreciated, thank you in advance

You can use getElementsByAttribute , then loop and filter:

var rels = getElementsByAttribute('rel');
var attr = 'external';

var result = [];
for (var i=0; i<rels.length; i++) {
  if (rels[i].getAttribute('rel').indexOf(attr) > -1) {
    result.push(rels[i]);
  }
}
