Common tips:
1. How can I leave a new window in the superconnection between showmodaldialog and showmodelessdialog?
Add <base target = "_ Self"> to the opened webpage. This sentence is generally placed between
Target = "" in the table at the same time must be blank.
2. How can I refresh the content in showmodaldialog and showmodelessdialog?
In showmodaldialog and showmodelessdialog, you cannot press F5 to refresh or bring up a menu. This depends on
Javascript. The following are relatedCode:
<Body onkeydown = "If (event. keycode = 116) {reload. Click ()}">
<A id = "reload" href = "filename.htm" style = "display: none"> reload... </a>
Replace filename.htm with the webpage name and place it in the webpage you opened. Press F5 to refresh the page.
Use with <base target = "_ Self">. Otherwise, press F5 to bring up a new window.
3. How to use JavaScript to close the window opened by showmodaldialog (or showmodelessdialog.
<Input type = "button" value = "close" onclick = "window. Close ()">
Also use <base target = "_ Self">. Otherwise, a new ie window will be opened and closed.
4. Math. Random and showmodaldialog.
When the pop-up page you set is fixed (as shown above)"Modal.htm" Page)Ie can easily download the next page (openpage.html) to the local file area without reloading,
For Dynamically Loaded pages, this often leads to misunderstandings. If data is not updated in time, it is not conducive to developer testing. Therefore, you can use the following method:
VaR strpage = "/medal.htm? Random = "+ math. Random ();
In this way, the strpage generated every time is different. The reason is self-evident.
