【jquery】jquery 在 ie6 下无法设置 select 选中的解决方法
本文主要解决在 ie6 下，jquery 无法设置 select 选中的问题。我们先看个例子：
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8"/>
<title>demo</title>
</head>
<body>
<select name="gameZone" id="gameZone">
<option value="0">请选择游戏大区</option>
<option value="1">游戏一区</option>
<option value="2">游戏二区</option>
</select>
</body>
</html>
<script type="text/javascript" src="/js/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$.each($('#gameZone > option'),function(){
if($(this).val() == '1'){
$(this).attr('selected','selected');
}
});
});
</script>
以上代码在所有浏览器中都没有问题，打开页面 select 会选中第二个选项。那么当 select 里的内容是动态添加的，又会是怎样的情况呢？
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8"/>
<title>demo</title>
</head>
<body>
<select name="gameZone" id="gameZone">
<option value="0">请选择游戏大区</option>
</select>
</body>
</html>
<script type="text/javascript" src="/js/jquery.min.js"></script>
<script type="text/javascript">
var servers ='[{"gm_id":33,"groups":[{"index":"1","name":"\u4f20\u4e16\u51b7\u6708","id":"game1"}],"id":"dx1","name":"\u7535\u4fe1\u4e00\u533a"},{"gm_id":39,"groups":[{"index":"3","name":"\u4ed9\u5251\u604b\u5f71","id":"game3"}],"id":"dx4","name":"\u7535\u4fe1\u4e8c\/\u4e09\/\u56db\/\u4e94\/\u516d\u533a"},{"gm_id":49,"groups":[{"index":"1","name":"\u7b11\u50b2\u5343\u53e4","id":"game1"}],"id":"dx7","name":"\u7535\u4fe1\u4e03\u533a\/\u516b\u533a\/\u4e5d\u533a"},{"gm_id":62,"groups":[{"index":"1","name":"\u98ce\u5f71\u76db\u5bb4","id":"game1"}],"id":"dx10","name":"\u7535\u4fe1\u5341\u533a"},{"gm_id":68,"groups":[{"index":"1","name":"\u70c8\u65e5\u661f\u5b87","id":"game1"},{"index":"3","name":"\u5929\u67a2\u661f\u8fb0","id":"game3"},{"index":"5","name":"\u7eb5\u5730","id":"game5"},{"index":"6","name":"\u91d1\u83b2","id":"game6"}],"id":"dx11","name":"\u7535\u4fe1\u5341\u4e00\u533a"}]';
function showZone(){
var serversLists = eval(servers);
var serversHtml = '<option value="0">请选择游戏大区</option>';
for(var i = 0; i < serversLists.length; i++){
serversHtml += '<option value="' + serversLists[i].id + '">' + serversLists[i].name + '</option>';
}
return serversHtml;
};
$(function(){
$('#gameZone').html(showZone());
$.each($('#gameZone > option'),function(){
if($(this).val() == 'dx1'){
$(this).attr('selected','selected');
}
});
});
</script>
我们可以看到在 chrome，firefox，ie8，ie7 这些浏览器都没有问题，但是在蛋疼的 ie6 浏览器中会 js 报错（无法设置 selected 属性，未指明的错误）。
解决方法有两种：setTimeout 和 try/catch
第一种：setTimeout（推荐）
<!DOCTYPE HTML>
<html lang="en-US">

</select>
</body>
</html>
<script type="text/javascript" src="/js/jquery.min.js"></script>
<script type="text/javascript">
var servers ='[{"gm_id":33,"groups":[{"index":"1","name":"\u4f20\u4e16\u51b7\u6708","id":"game1"}],"id":"dx1","name":"\u7535\u4fe1\u4e00\u533a"},{"gm_id":39,"groups":[{"index":"3","name":"\u4ed9\u5251\u604b\u5f71","id":"game3"}],"id":"dx4","name":"\u7535\u4fe1\u4e8c\/\u4e09\/\u56db\/\u4e94\/\u516d\u533a"},{"gm_id":49,"groups":[{"index":"1","name":"\u7b11\u50b2\u5343\u53e4","id":"game1"}],"id":"dx7","name":"\u7535\u4fe1\u4e03\u533a\/\u516b\u533a\/\u4e5d\u533a"},{"gm_id":62,"groups":[{"index":"1","name":"\u98ce\u5f71\u76db\u5bb4","id":"game1"}],"id":"dx10","name":"\u7535\u4fe1\u5341\u533a"},{"gm_id":68,"groups":[{"index":"1","name":"\u70c8\u65e5\u661f\u5b87","id":"game1"},{"index":"3","name":"\u5929\u67a2\u661f\u8fb0","id":"game3"},{"index":"5","name":"\u7eb5\u5730","id":"game5"},{"index":"6","name":"\u91d1\u83b2","id":"game6"}],"id":"dx11","name":"\u7535\u4fe1\u5341\u4e00\u533a"}]';
function showZone(){
var serversLists = eval(servers);
var serversHtml = '<option value="0">请选择游戏大区</option>';
for(var i = 0; i < serversLists.length; i++){
serversHtml += '<option value="' + serversLists[i].id + '">' + serversLists[i].name + '</option>';
}
return serversHtml;
};
$(function(){
$('#gameZone').html(showZone());
setTimeout(function(){
$.each($('#gameZone > option'),function(){

$(this).attr('selected','selected');
}
});
},1);
});

});
