去除54kefu的链接，使其不可点

<script type="text/javascript">
window.onload = function() {
for (jL in document.links) {
 //alert(jL); break;
 if (document.links[jL].href.indexOf('54kefu.net') != -1) {
 document.links[jL].href = "javascript:void(0)";
 document.links[jL].setAttribute('target','_self');
 }
}
}
</script>
