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.

 
 
<title>jquery xml解析</title> 
<script javascript></script> 
<script> 
$(
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+""); 
}); 
} 
}); 
$("#DropProvince").change(function(){ 
$("#sCity>option").remove(); 
var pname = $("#DropProvince").val(); 
$.ajax({url:"City.xml", 
success:function(xml){ 
$(xml).find("province[name=&#39;"+pname+"&#39;]>city").each(function(){ 
$("#sCity").append("<option>"+$(this).text()+""); 
}); 
} 
}); 
}); 
}); 
</script> 
 
 

 

    请选择       

 

   

city.xml file

<?xml  version="1.0" encoding="utf-8" ?> 
<provinces> 
<province> 
<city>武汉</city> 
<city>黄石</city> 
<city>宜昌</city> 
<city>天门</city> 
</province> 
<province> 
<city>邵阳</city> 
<city>长沙</city> 
<city>岳阳</city> 
</province> 
<province> 
<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> 
$(document).ready(function () { 
$.ajax({ 
url: "City.xml", 
success: function (xml) { 
$(xml).find("province").each(function () { 
var t = $(this).attr("name"); 
$("#DropProvince").append("<option>" + t + ""); 
}); 
} 
}); 
$("#DropProvince").change(function () { 
$("#sCity>option").remove(); 
var pname = $("#DropProvince").val(); 
$.ajax({ 
url: "City.xml", 
success: function (xml) { 
$(xml).find("province[name=&#39;"+pname+"&#39;]>city").each(function(){ 
$("#sCity").append("<option>"+$(this).text()+""); 
}); 
} 
}); 
}); 
}); 
</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.
