Getelementsbyclassname compatible with IE 8

1 functiongetelements (node, className, item) {2         if(node.getelementsbyclassname) {3             returnNode.getelementsbyclassname (ClassName) [item];4}Else {5             varResults =NewArray ();6             varallele = node.getelementsbytagname (' * '));7              for(vari = 0, L = allele.length; I < L; i++) {8                 if(Allele[i].classname.indexof (className)! =-1) {9 Results.push (Allele[i]);Ten                 } One             } A             returnResults[item]; -         } -}

ClassName represents the class name of the element node to get, item represents the ordinal of the element node to get (default starting from 0)

Instance:

1 <ul>2         <li class= "Li-element" >111</li>3         <li class= " Li-element ">222</li>4         <li class=" Li-element ">333</li>5         <li class= "Li-element" >444</li>6     </ul>

To get the third Li element in UL node, first get the UL element node, var ulelement=document.getelementsbytagname (' ul ') [0];

Then get the third Li node, var lielement=getelementsbyclassname (ulelement, ' li-element ', 2);

Bo Master is learning JavaScript, if there are shortcomings, hope to point out.
