Detailed explanation of jQuery parsing xml files
This time I will bring you a detailed explanation of jQuery parsing xml files. What are the precautions for jQuery parsing xml files? The following is a practical case, let's take a look.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>jquery xml解析</title>
<script src="jquery.min.js" type="text/
javascript
"></script>
<script type="text/javascript">
$(
document
).ready(function(){
$.ajax({url:"City.xml",
success:function(xml){
$(xml).find("province").each(function(){
var t = $(this).attr("name");//this->
$("#DropProvince").append("<option>"+t+"</option>");
});
}
});
$("#DropProvince").change(function(){
$("#sCity>option").remove();
var pname = $("#DropProvince").val();
$.ajax({url:"City.xml",
success:function(xml){
$(xml).find("province[name='"+pname+"']>city").each(function(){
$("#sCity").append("<option>"+$(this).text()+"</option>");
});
}
});
});
});
</script>
</head>
<body>
<form id="form1">
<p>
<select id="DropProvince" style="width:60px;">
<option>请选择</option>
</select>
<select id="sCity" style="width:60px;">
</select>
</p>
</form>
</body>
</html>
city.xml file
<?xml version="1.0" encoding="utf-8" ?> <provinces> <province name="湖北"> <city>武汉</city> <city>黄石</city> <city>宜昌</city> <city>天门</city> </province> <province name="湖南"> <city>邵阳</city> <city>长沙</city> <city>岳阳</city> </province> <province name="广东"> <city>广州</city> <city>深圳</city> </province> </provinces>
In fact, the main thing is to pay attention to how to parse the xml file on the html interface. The format is
<script type="text/javascript">
$(document).ready(function () {
$.ajax({
url: "City.xml",
success: function (xml) {
$(xml).find("province").each(function () {
var t = $(this).attr("name");
$("#DropProvince").append("<option>" + t + "</option>");
});
}
});
$("#DropProvince").change(function () {
$("#sCity>option").remove();
var pname = $("#DropProvince").val();
$.ajax({
url: "City.xml",
success: function (xml) {
$(xml).find("province[name='"+pname+"']>city").each(function(){
$("#sCity").append("<option>"+$(this).text()+"</option>");
});
}
});
});
});
</script>Use $.ajax() to call the content of the xml file. Then $.each() performs a loop operation. The basic idea is this. After success, execute the success callback function. The xml file here is used to store data, which is equivalent to reading the file in the database. I believe you have mastered the method after reading the case in this article.
