我正在使用 casperjs 来获取页面上的所有 jquery ui 选项卡并单击每个选项卡。问题是选项卡是动态加载的，并且似乎永远不会从“正在加载...”状态切换。我尝试过使用 casperwait()函数甚至waitWhileSelector() 函数，但似乎都不起作用：
function getActiveTab () {
var active_tab = $('#tabs>ul').find('li.ui-tabs-selected').text();
console.log("Active tab: " + active_tab);
return active_tab;
}
function clickTabs (tabs) {
this.each(tabs, function(casper, tab_name, i){
var child_number = i + 1;
var tab_selector = "#tabs>ul>li:nth-child(" + child_number + ")>a";
console.log(tab_selector);
// this.thenClick(tab_selector).waitWhileSelector('#tabs>ul>li.ui-state-processing', function(){
this.thenClick(tab_selector, function(){
var this_tab = this.evaluate(getActiveTab);
});
});
}
它似乎适用于第一个选项卡（因为它是在页面加载时加载的），但所有其余选项卡都返回“正在加载”：

当我使用 waitWhileSelector 时，它会在第一次单击后超时。大多数选项卡动态加载带有 dataTables 对象的脚本标记，并且似乎永远不会加载表对象或未加载数据表库？我是否必须将该库注入评估方法，或者页面中的标签是否应该将其拉入？
我将不胜感激任何帮助隔离此测试中发生的事情。
