Getbyclass method compatible with low version ie

ECMA5 provides us with a practical getelementsbyclassname () method, but unfortunately this method is directly hung up under the low version of IE.

Do not rely on JQ, the premise of the implementation of the method,

functionGetbyclass (oparent,sclass) {if(oparent.getelementsbyclassname) {//this is in addition to the DOM collection, an array of classes, not an array        returnOparent.getelementsbyclassname (Sclass); }        varresult = []; varRe =NewREGEXP ("\\b" +sclass+ "\\b"); varAele = Oparent.getelementsbytagname ("*");  for(vari = 0; i < aele.length; i++){        if(Re.test (aele[i].classname)) {Result.push (aele[i]); }    }        //this is in addition to returning an array    returnresult;} 

It is important to note that the object returned by the advanced browser and the low-level browser is different.
