我正在使用AJAX和Jquery将json对象加载到我的网页中。它工作得很好但是它在json数据中加载到我的页面的时间有50-70%,它将第二组数据附加到我的页面,有没有一种方法可以确保我的数据只加载一次?
我最初的想法是让json调用同步而不是异步,但听起来不对,是否有更好的方法呢?
$('#myResource').click(function() {
$.getJSON("data/preachers.json", function(result) {
$.each(result, function(i, field) {
$("#preachers").append( function() {
var preacher = '<div class="box box1">';
preacher += '<div class="image">';
preacher += '<a href=' + '"' + (field.link) + '"' + ' target="_blank">';
preacher += '<img src= "img/resources/' + (field.image) + '" alt="' + (field.name) + '" class="resource_image">';
preacher += '</a>';
preacher += '</div>'; //class = image
preacher += '<div class="text">';
preacher += '<p><h2>' + (field.name) + '</h2>';
preacher += (field.details) + '</p>';
preacher += '</div>'; //class=text
preacher += '</div>'; //class=box
return preacher;
});
});
});
});

在一些评论的帮助下,答案最终是我需要在函数开头取消绑定点击,并使其保持未绑定状态:
$('#myResource').click(function() {
$( "#myResource").unbind( "click" );
$.getJSON("data/preachers.json", function(result) {
$.each(result, function(i, field) {
console.log('load everything');
$("#preachers").append( function() {
var preacher = '<div class="box box1">';
preacher += '<div class="image">';
preacher += '<a href=' + '"' + (field.link) + '"' + ' target="_blank">';
preacher += '<img src= "img/resources/' + (field.image) + '" alt="' + (field.name) + '" class="resource_image">';
preacher += '</a>';
preacher += '</div>'; //class = image
preacher += '<div class="text">';
preacher += '<p><h2>' + (field.name) + '</h2>';
preacher += (field.details) + '</p>';
preacher += '</div>'; //class=text
preacher += '</div>'; //class=box
return preacher;
});
});
});
});
