我需要的是通过javascript重建prototype.js Ajax请求。(没有 jQuery / 没有获取)。需要 IE 支持(出于某些原因...)
new Ajax.Request(
urlVar,
{
method: 'post',
parameters: {elid: document.getElementById('element').selectedIndex},
onCreate: function(){
//do somethings
},
onComplete: fucnction (event){
currentValues = eval('(' + event.responseText + ')');
console.log(currentValues); // will give me an array with 3 objects
}
});
我尝试过的是:
var xhr = new XMLHttpRequest();
xhr.open("POST", urlVar, true);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function (event) {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
currentValues = eval('(' + event.responseText + ')');
console.log(currentValues); // i see an error that "currentValues" is undefined
//i can get 1 object if i will do eval('(' + THIS.responseText + ')');
// but it still bugs me a lot..
//other actions here
}
else if (xhr.status == 400) {
console.log('ERROR')
}
else {
console.log('something else other than 200 was returned');
}
}
}
xhr.send(document.getElementById('element').selectedIndex);
也许有人知道在这种情况下哪种结构会起作用。有什么方法可以通过 js 执行 onCreate / onComplete 吗?
