如果点击两次，则在同一个窗口中加载_blank链接 [英] Load _blank link in the same window if clicked twice

问题描述

是否有可能？

所以我有一个链接：

< ; a href ='/ page.htm'target ='_ blank'>

如果他们点击两次，空白标签。有没有办法让这个特定的链接每次都加载到同一个新选项卡中？

解决方案

您可以分配一个 onclick 处理程序添加到调用窗口对象的 open 方法的锚点。第一次点击锚时，它会打开一个新的浏览标签。

注意的第二个参数打开方法（即其他窗口）。这是新选项卡的句柄。如果要将新内容加载到该选项卡中（而不是打开另一个选项卡），只需使用与第二个参数相同的句柄再次调用 open 方法：

 （function（）{
 
 var childWindowOpen = false; 
 
 window.onload = function（event）{
 var anchor = document.getElementById（child-window-link）; 
 
 anchor.onclick = function（event）{
 var childWindow; 
 
 if（！childWindowOpen）{
 childWindow = window.open（otherpage.html，other-window）; 
} else {
 childWindow = window.open（yetanotherpage.html，other-window）; 
} 
 childWindowOpen = true; 
 return false; 
} 
}; 
}（））; 
  

Is it possible?

So I have a link:

<a href='/page.htm' target='_blank'>

If they click it twice, it will load up two blank tabs. Is there anyway to get this particular link to load in the same new tab each time?

解决方案

You can assign an onclick handler to the anchor that calls the open method of the window object. The first time the anchor is clicked, it opens a new browsing tab.

Notice the second parameter to the open method (i.e., "other-window"). This is a handle to the new tab. If you want to load new content into that tab (instead of opening yet another tab), just call the open method again with that same handle as the second parameter:

(function () {

    var childWindowOpen = false;

    window.onload = function (event) {
        var anchor = document.getElementById("child-window-link");

        anchor.onclick = function (event) {
            var childWindow;

            if (!childWindowOpen) {
                childWindow = window.open("otherpage.html", "other-window");
            } else {
                childWindow = window.open("yetanotherpage.html", "other-window");
            }
            childWindowOpen = true;
            return false;
        }
    };
}());
