问题描述
我目前正在使用jquery和回调函数进行AJAX调用，以在AJAX调用之外检索结果，并且在尝试使用循环从提供的json文件(ticker.json)中打印更多数据时遇到了麻烦在这里:
I'm currently doing an AJAX call with jquery and callback functions to retrieve a result outside of the AJAX call and I am having trouble in attempting to use a loop to printout more data from my json file (ticker.json) provided here:
{
"test": {
"msgOne": [
"Remote One",
"Remote Two",
"Remote Three"
],
"msgTwo": "Remote2",
"msgThree": "Remote3"
}
}
我的代码也在下面:
<html>
<head>
<title>Weather Data for Emergency Models</title>
<script src="jquery-1.9.1.min.js" type="text/javascript"></script>
</head>
<body>
<script Language="JavaScript">
function hmm(callback) {
$.ajax({
url : 'ticker.json', // ___ |I want to loop this
dataType: 'json', // | |index as a variable
success: function(response) { // v
result = response['test']['msgOne'][2];
callback(result);
}
});
}
hmm(function(result) {
document.write(result); //currently outputs as "Remote Three"
});
</script>
</body>
</html>
主要问题是我想使用回调函数继续异步运行，并循环遍历json文件中的"msgOne"数组，然后将所有三个结果依次打印到网页上.之前，我曾尝试在多个地方引入for循环，但我一直遇到错误.我意识到还有其他方法可以执行此操作，但是在需要的条件下(异步和回调函数，因为我希望最终将此方法应用于列表中多个网站上找到的json文件的jsonp)，是否可以执行此操作?我最终想要修改给定的代码以处理数组和更复杂的代码.
The main problem is that I want to continue as asynchronous using the callback functions and loop through the "msgOne" array in the json file and print out all three results to the webpage sequentially. I have tried introducing a for-loop in multiple places previously, but I keep getting errors. I realize there are other ways to do this, but under the wanted conditions (asynchronous & callback functions because I want to eventually apply this to jsonp for json files found on multiple websites on a list), is there a way to do this? I ultimately want to modify the given code to deal with arrays and more complex code.
推荐答案
尝试一下-在您的success
success: function(response) {
callback(response);
}
和您的function
hmm(function(result) {
$.each(result.test.msgOne,function(i,v){
document.write(v);
});
});
