The Pop-up Blocking feature blocks pop-up (and pop-under) windows initiated automatically by a Web site. Internet Explorer blocks Pop-up windows in the by default. However, the Pop-up Blocker enables pop-up windows initiated by a user action. Users can configure Internet Explorer 6 for Windows XP with SP2 to be more or less restrictive. Users can also turn off the Pop-up Blocker altogether. Generally, the Pop-up Blocker enables a window to open under the following circumstances:
• |
When initiated by user action, such as clicking a button or hyperlink |
• |
When opened in the (considered safe) |
• |
When opened by other applications running on the local computer |
The affected script methods are:
window.open window.showHelp window.showModalDialog window.showModelessDialog window.external window.NavigateAndFind
注: |
|
Pop-ups created with window.createPopup are unaffected by the Pop-up Blocker. |
在web编程过程中,经常会遇到一些页面需要弹出窗口,但是在服务器端用window.open弹出的窗口会被IE阻止掉,弹出的窗口有时并不能满足我们需要,我们需要弹出新的浏览器窗口。
为什么我们编写的弹出窗口会被IE阻止呢,原来IE会自动判断弹出窗口的状态,它会阻止自动弹出的窗口,而通过我们用鼠标点击弹出的窗口,它是不会阻止的。这里就有一个问题,有人说:我的程序是写在服务器按钮里的,也是通过鼠标点击弹出的呀!其实只有在加载页面后,我们点击到弹出这段时间页面没有被重新加载的情况下,弹出的窗口才不会被阻止!这也就是说,写在服务器控件的回传事件里的window.open都会被阻止。
继续Google解决办法,在分析了几种解决方法并进行对比之后,发现最简单有效的方法如下:
在window.open()函数中增加一个参数,将target设置为‘self’,
即改为使用: window.open(link,'_self');
问题解决。
