页面载入时用jquery选择器找到相应的option对其进行点击。
<code>$(function(){ $(option).click(); })</code>
Copy after login
可以用jQuery的trigger()方法触发
$(document).ready(function(){ $('select').find('option:eq(0)').select(function(){ alert('加载ajax'); }); $('select').find('option:eq(0)').trigger('select'); });
Copy after login
html页
js
function Change(){
<code>var strvalue=$("#sel").val(); $.ajax({ url: "/Main/Func?valu="+strvalue, type: "POST", dataType: "json", success: function (jdata, stat) { alert("成功"); } });</code>
Copy after login
}
