type: arguments[0].type || "GET",
url: arguments[0].url || "",
async: arguments[0].async || "true",
data: arguments[0].data || null,
dataType: arguments[0].dataType || "text",
contentType: arguments[0].contentType || "application/x-www-form-urlencoded",
beforeSend: arguments[0].beforeSend || function () { },
success: arguments[0].success || function () { },
error: arguments[0].error || function () { }
}
ajaxData.beforeSend()
var xhr = createxmlHttpRequest();
xhr.responseType = ajaxData.dataType;
xhr.open(ajaxData.type, ajaxData.url, ajaxData.async);
xhr.setRequestHeader("Content-Type", ajaxData.contentType);
xhr.send(convertData(ajaxData.data));
xhr.onreadystatechange = function () {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
ajaxData.success(xhr.response)
} else {
ajaxData.error()
}
}
}
}
function createxmlHttpRequest() {
if (window.ActiveXObject) {
return new ActiveXObject("Microsoft.XMLHTTP");
} else if (window.XMLHttpRequest) {
return new XMLHttpRequest();
}
}
function convertData(data) {
if (typeof data === ‘object‘) {
var convertResult = "";
for (var c in data) {
convertResult += c + "=" + data[c] + "&";
}
convertResult = convertResult.substring(0, convertResult.length - 1)
return convertResult;
} else {
return data;
}
}
ajax({
type: "POST",
