js 中使用el表達式 關鍵總結：在js中使用el表達式一定要加雙引號

js控制中用到了el表達式，最開始源碼如下：

1. var selected = ${requestScope.xxxxForm.recordNumPerPage}

1. var selected = “${requestScope.xxxxForm.recordNumPerPage}”

1. function getSelected(name){
2. var selects = document.getElementsByName(name);
3. var selected = “${requestScope.xxxxForm.recordNumPerPage}";
4. if(selected == undefined || selected == null || selected ==""){
5. return false;
6. }
7. for(var j = 0; j < selects.length; j++ ){
8. for(var i = 0; i = selects[j].length; i++){
9. if(selects[j].options[i].value == selected){
10. selects[j].options[i].selectd = true;
11. }
12. }
13. }
14. }
