Question

我正在使用UIWebview，在选择下拉列值时会有一些下拉菜单。我正在调用javascript警报它冻结了iPad中的应用程序。点击设备主页按钮＆amp;打开应用程序取消冻结应用程序

<cfcontent reset="true" /><!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=320, initial-scale=3">
<title>freeze!</title>
</head>
<body>
</div>
<div style="height: 100px;">
    &lt;select> with onchange event
    <select id="select" onchange= "actualFunction()">
        <option value="ONE">one</option>
        <option value="TWO">two</option>
        <option value="THREE">three</option>
    </select>
app freezes on selection because of javascript blocking onchange 
event
</div>  <!--- <div style="clear: both;"></div>
<div style="width: 25%; float: left;">
    <select id="three">
        <option value="ONE">one</option>
        <option value="TWO">two</option>
        <option value="THREE">three</option>
    </select>
</div> --->

js function
function actualFunction()
{
    if(document.getElementById('select').value !="d")
    {
        alert('yes');
    }
}

从uiwebview中选择值时降低冻结
