如何使用xmlhttprequest与flask进行数据交互

Answer 1

//第一步：创建XMLHttpRequest对象
var xml;
var resultNode =document.getElementById("result");
if(window.XMLHttpRequest) {
xml = new XMLHttpRequest();
if (xml.overrideMimetype){
xml.overrideMimeType("text/xml");
}
} else if(window.ActiveXObject) {
var MSXML = ['MSXML2.XMLHTTP.6.0', 'MSXML2.XMLHTTP.5.0', 'MSXML2.XMLHTTP.4.0',
'MSXML2.XMLHTTP.3.0', 'MSXML2.XMLHTTP', 'Microsoft.XMLHTTP'];
for (var n = 0; n <MSXML.length; n++) {
try {
xml = newActiveXObject(MSXML[n]);
break;
}
catch (e) {
}
}
}
if(xml == null){
resultNode.innerHTML = "不能建立XMLHttpRequest对象";
return false;
}
