我认为我相当接近，我已经看过一些将外部 JSON 文件集成到带有 Mustache 的 html 中的示例，但目前它不起作用。 JSON 文件充满了琐碎的问题，这是我尝试链接的示例问题:
{
"jsonquestions": [
{
"id":1,
"q_category_id":0,
"q_text":"Which of the following is regar-ded as the real founder of portugese power in India",
"q_options_1":"Pedro Cabral",
"q_options_2":"Almeida",
"q_options_3":"Vasco da Gama",
"q_options_4":"Alfonso de Albuquerque",
"q_correct_option":4,
"q_difficulty_level":2,
"q_date_added":"2013-06-10T04:00:00.000Z"
}
]
}
该文件名为 questions.json，我正在尝试将其链接到此 html 表:

我有什么遗漏的吗？谢谢。
最佳答案
看起来您缺少“渲染”函数调用 Mustache.render(template, data); (to_html 基本上已被弃用)我构建了一个部分 Plunker展示它的工作原理，它嵌入在下面。我将 json 托管在 https://api.myjson.com/bins/2oxsm
// Code goes here
$(function(){
var data;
$.getJSON("https://api.myjson.com/bins/2oxsm")
.done(function(dat) {
data = dat;
console.log("success",dat)
render();
})
.fail(function() {
console.log( "error",arguments);
})
.always(function() {
console.log( "complete" );
});
function render(){
// mustache
var tmpl = $('#questions-template').html();
var html = Mustache.render(tmpl, data);
$('#questions').find('tbody').html(html);
}
});
// lets make them clickable
$(function(){
var choices = [];
$(document).on("click","td.choice",updateAnswers)
function updateAnswers(e){
var $t = $(this),
$p = $t.parents('tr'),
$answer = $p.find('.answer'),
correct = $answer.data('value'),
good = $t.data('value') === correct;
$p.find('td')
.toggleClass("checked",false)
.toggleClass("correct",false);
$t.addClass("checked");
$answer.toggleClass("correct",good);
$t.toggleClass("correct",good);
$("#choices").html('');
$('td.checked').each(show);
}
function show(i,v){
// send this data to the backend?
var $v = $(v),
$p = $v.parents('tr'),
div = $("<div/>").html($p.index()+1 + ":" + $v.html());
$("#choices").append(div);
div.toggleClass('correct',$v.is(".correct"))
}
})
