n00b？ HREF = JavaScript的 [英] n00b ? href=javascript

问题描述

任何人都可以解释为什么当我在页面上有超链接时，代码

类似于下面，在用户点击链接后，所需的窗口

打开但是带有超链接的页面更改为一个新页面，其中只有

值" [object]"在上面？我希望原始页面保持不变....

感谢您对javascript的见解n00bie ... :)


< a href = javascript ：window.open（''wireless.htm''，''pjtdetails''，

config =''height = 400，width = 400，toolbar = no，menubar = no，scrollbars = yes，

resizable = yes，location = no''）">

asdfalkjsdflbkajsdf< / a>

Can anybody explain why when I have a hyperlink on a page with the code
similar to below, after the user clicks on the link, the desired window
opens but the page with the hyperlink changes to a new page with simply the
value "[object]" on it? I want the original page to remain unchanged....
thanks for the insight to a javascript n00bie... :)

<a href="javascript:window.open(''wireless.htm'', ''pjtdetails'',
config=''height=400, width=400, toolbar=no, menubar=no, scrollbars=yes,
resizable=yes, location=no'')">
asdfalkjsdflbkajsdf</a>

推荐答案

试试这个:(全部在一行）


< a HREF ="＃" onClick =" window.open（''wireless.htm''，

''pjtdetails''，''height = 400，width = 400，toolbar = no，menubar = no，

scrollbars = yes，resizable = yes，location = no''）">点击我< / a>

感谢javascript n00bie的洞察力... :)


这是使用javascript的危险之一 ：URI。使用onclick事件处理程序的方法更好：


< A href ="" onclick =" window.open（...）; return false"> text< / A>


注意语句''return false''？这也需要停止

浏览器跟随链接（href =""与当前页面相同）。

除非有特殊原因要使用链接，你应该使用一个按钮

代替：


< BUTTON type =" button" onclick =" window.open（...）"> text< / BUTTON>


请注意，不需要return语句。


这个故事的寓意是，永远不要使用javascript ：URI。

< a href =" javascript ：window。 open（''wireless.htm''，''pjtdetails''，
config =''height = 400，width = 400，toolbar = no，menubar = no，scrollbars = yes，
resizable =是的，location = no''）">
asdfalkjsdflbkajsdf< / a>

similar to below, after the user clicks on the link, the desired window
opens but the page with the hyperlink changes to a new page with simply
the
value "[object]" on it? I want the original page to remain unchanged....

This is one of the hazards of using javascript: URIs. The better method is
using the onclick event handler:

<A href="" onclick="window.open(...);return false">text</A>

Notice the statement, ''return false''? This is also required to stop the
browser from following the link (href="" is the same as the current page).
Unless there is a specific reason to use a link, you should use a button
instead:

<BUTTON type="button" onclick="window.open(...)">text</BUTTON>

Notice that the return statement is not needed.

The moral of this story is, NEVER use javascript: URIs.
<a href="javascript:window.open(''wireless.htm'', ''pjtdetails'',
config=''height=400, width=400, toolbar=no, menubar=no, scrollbars=yes,
resizable=yes, location=no'')">
asdfalkjsdflbkajsdf</a>

''features''字符串（height = 400，。 ..）不应该包含任何空格。那个

，应写成：


" height = 400，width = 400，滚动条，可调整大小


另请注意，我省略了禁用的功能。布尔（是/否）选项

默认为'no'时遗漏。

The ''features'' string (height=400,...) shouldn''t contain any spaces. That
is, it should be written:

"height=400,width=400,scrollbars,resizable"

Also notice that I omitted the disabled features. Boolean (yes/no) options
default to ''no'' when left out.

这仍有问题;你不能取消这个活动。打开新窗口

后，原始页面仍会被更改。当然，它返回到同一页面的
，但在这种情况下它根本不会发生。

此外，不应该有任何空格在''features''字符串中。你将
附加到处理程序代码中（包括分号）：


;返回false

This still has a problem; you don''t cancel the event. Once the new window
is opened, the original page will still be changed. Granted, it goes back
to the same page, but it shouldn''t happen at all, in this case.
Furthermore, there shouldn''t be any spaces in the ''features'' string. You
should append the following to the handler code (including the semi-colon):

;return false
