问题描述
如何在不使用jQuery的情况下重写此代码?我需要在移动应用程序中执行此操作,我无法使用jQuery。
How can I rewrite this code without using jQuery? I need to do it in a mobile app where I can't use jQuery.
$.ajax({
type: "POST",
url:"../REST/session.aspx?_method=put",
data: JSON.stringify(dataObject, null,4),
cache: false,
dataType: "json",
success: onSuccessLogin,
error: function (xhr, ajaxOptions){
alert(xhr.status + " : " + xhr.statusText);
}
});
推荐答案
你可以试试这个:
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) {
// What you want to do on failure
alert(xmlhttp.status + " : " + xmlhttp.responseText);
}
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
// What you want to do on success
onSuccessLogin();
}
}
xmlhttp.open("POST", "../REST/session.aspx?_method=put", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.setRequestHeader("Cache-Control", "no-cache"); // For no cache
xmlhttp.send("data=" + JSON.stringify(dataObject, null,4));
至于如何在没有jQuery库的情况下只用javascript做更多东西看看或
As for how to do more stuff with only javascript without jQuery library take a look at W3Schools AJAX Tutorial or Mozilla - Using XMLHttpRequest
正如duri所说,你将不得不找到一种方法将dataObject转换为字符串,而不是全部浏览器支持JSON对象。
And as duri said, you will have to find a way to convert dataObject to string, as not all browsers support JSON object.
