[英]Set html form fields from json data via ajax
This function grabs json from the server as a response. 该函数从服务器获取json作为响应。 What I want to do is to set html form fields using this ajax function. 我想要做的是使用此Ajax函数设置html表单字段。
function getProfile()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
//This is the json response
alert(xmlhttp.responseText);
//Set html form fields, but how?
}
}
xmlhttp.open("POST","http://localhost:8080/SampleApp/user/profile",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send();
}
Sample html form: 样本HTML表单:
<html>
......//
......//
<form id="1" name="1">
FName:<input type="text" name="txt1" id="txt1">
LName:<input type="text" name="txt2" id="txt2">
.................//
..............//
</form>
</html>
The goal can be achieved through the following code: 可以通过以下代码实现目标:
function getProfile()

var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}

xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var jsonVar=xmlhttp.responseText;
obj = JSON && JSON.parse(jsonVar) || $.parseJSON(jsonVar);
document.getElementById("txt1").value=obj.name;
document.getElementById("txt2").value=obj.email;
//keep on going
}
}
xmlhttp.open("POST","http://localhost:8080/SampleApp/user/profile",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send();
}
