- return 0;
- });
- data = "";
- for(var i=0; i < name_list.length; i++){
- data += "<li class='list-group-item'>"+name_list[i]+"</li>";
- }
- document.getElementById('list').innerHTML = data;
- }
- function searchResult(){
- var search = document.getElementById('search').value.toLowerCase();
- var target = document.getElementById("list");
- var list = target.getElementsByTagName('li');
- for(var i=0; i < list.length; i++){
- var text = list[i].innerHTML;
- if(text.toLowerCase().indexOf(search) > -1){
- list[i].style.display = "";
