如何使用jQuery在JSON ajax请求中回调404上的函数？

我想用JSON中的响应发出Ajax请求。 所以我提出了这个Ajax请求： $.ajax({ url: ‘http://my_url’, dataType: “json”, success: function(data){ alert(‘success’); }, error: function(data){ alert(‘error’); }, complete: function(data) { alert(‘complete’) }}) 这段代码工作正常但是当我的url发送给我一个HTTP代码404时，没有使用回调，甚至是完整的回调。 经过研究，这是因为我的dataType是’json’所以404返回是HTML并且JSON解析失败了。 所以没有回调。 有一个解决方案在404被引发时调用回调函数吗？ 编辑：完成回调不调用返回是404.如果你想要一个URL机智404你可以打电话： http ： //twitter.com/status/user_timeline/jksqdlmjmsd.json？count = 3＆ callback = jsonp1269278524295＆_ = 1269278536697这是这个url我有我的问题。

使用ajax json数据创建高清

我正在尝试使用mysql脚本检索的mysql数据在页面中创建一个简单的图表 我不明白如何将ajax调用与图表所需的数据集成。 我不太了解各种图表插件，让我的生活变得轻松，目前正在试用高级图表。 我的php脚本返回以下json： [{“name”:”golfers”},{“data”:[5.7879,6.6286,6.1724,5.3125,7.1481,6.1333,4.5769]}] 我的图表脚本是： $(function () { visitorData(function(data) { console.info(data); $(‘#chart1’).highcharts({ chart: { type: ‘column’ }, title: { text: ‘Average Visitors’ }, xAxis: { categories: [‘Monday’, ‘Tuesday’, ‘Wednesday’, ‘Thursday’, ‘Friday’, ‘Saturday’, ‘Sunday’] }, yAxis: { title: { text: ‘Number of visitors’ } }, series: data, }); }); }); 我的函数来进行ajax调用： $.ajax({ url: ‘/visitdata’, type: […]

获得原始目标的最佳方式

什么是jQuery喜欢和/或最佳实践方式来获取jQuery（或一般的浏览器javascript）中的事件的原始目标。 我一直在用这样的东西 $(‘body’).bind(‘click’, function(e){ //depending on the browser, either srcElement or //originalTarget will be populated with the first //element that intercepted the click before it bubbled up var originalElement = e.srcElement; if(!originalElement){originalElement=e.originalTarget;} }); 哪个有效，但我对两线function嗅探并不满意。 有没有更好的办法？

隐藏Highcharts和jQuery中的_groups_系列：如何获得可接受的性能？

我正在使用Highcharts来表示时间序列组。 因此，从同一个体收集的数据点通过线连接，并且来自属于同一组的个体的数据点共享相同的颜色。 Highcharts图例显示了每个单独的时间序列而不是组，而且我有超过一百个时间序列，以这种方式隐藏和显示数据是丑陋和不切实际的。 相反，我制作了按钮并使用jQuery将它们与在时间序列中搜索匹配颜色的函数相关联，并切换每个匹配系列的可见性。 以下是一个包​​含小数据集的示例： http ： //jsfiddle.net/bokov/VYkmg/6/ 以下是该示例中的系列隐藏function： $(“#button”).click(function() { if ($(this).hasClass(“hideseries”)) { hs = true; } else { hs = false; } $(chart.series).each(function(idx, item) { if (item.color == ‘green’) { if (hs) { item.show(); } else { item.hide(); } } }); $(this).toggleClass(“hideseries”); }); 以上工作。 问题是，我的真实数据可能有超过一百个单独的时间序列，看起来像检查每个系列的颜色真的很慢。 那么，有人能提出一种更有效的方法来解决这个问题吗？ 是否有一些内置的Highcharts方法已经这样做了？ 或者，我可以给jQuery一个更具体的选择器吗？ 我试着深入研究由Highcharts创建的元素，但我无法弄清楚哪些子元素对应于图表中的系列。 谢谢。

jQuery on（）stopPropagation不工作？

我似乎无法让这个停止传播.. $(document).ready(function(){ $(“body”).on(“click”,”img.theater”,function(event){ event.stopPropagation(); $(‘.theater-wrapper’).show(); }); // This shouldn’t fire if I click inside of the div that’s inside of the // `.theater-wrapper`, which is called `.theater-container`, anything else it should. $(“.theater-wrapper”).click(function(event){ $(‘.theater-wrapper’).hide(); }); }); 请参考这个jsfiddle
