jquery点击href链接 - 必须点击两次 [英] jquery click on href link - have to click twice

问题描述

此函数可以正常工作，但只有在按钮被点击两次后，弹出框才会打开（然后，后续点击会获得第一次点击的操作）。

The function works, but the popup will open only after the button is clicked twice (and then, subsequent clicks get the action on the first click).

$(document).ready(function(){
    $('a#printPosBtn').on('click', function(e) {
        e.preventDefault();
        $('.printPopup').popupWindow({ 
            centerBrowser:1,
            height:500,
            width:720,
            scrollbars: 1,
            resizable: 1
        });
        return false;
    });
});

有什么问题？

推荐答案

我认为这是因为你实际上在点击处理程序中初始化插件。从快速浏览到 popupWindow 文档，看起来插件会为你绑定点击处理程序意味着您的第一次点击绑定弹出功能（包括onclick处理程序），因此它只适用于第二次点击。我会尝试：

I think that is because you are actually initialising the plugin within the click handler. From a quick skim through the popupWindow docs it appears that the plugin takes care of binding a click handler for you, which means that your first click binds the popup functionality (including an onclick handler) so it only works upon click a second time. I would try:

$(document).ready(function() {

    $(".printPopup").popupWindow({
        centerBrowser: 1,
        height: 500,
        width: 720,
        scrollbars: 1,
        resizable: 1
    });

    // open popup by clicking on some other element
    $('#printPosBtn').on('click', function(e) {
        e.preventDefault();
        $(".printPopup").click();         
    });

});​
