问题描述
我正在使用javascript打开一个新窗口并将内容写入新窗口。部分内容是javascript文件，但javascript不会在新窗口中执行。帮助？
open.html：
< script >
function winopen（）
{
var ghtml =< h1 > sasaasas < / h1 > ;
var gwin = window.open（，_ blank，location = no，width = 1000，height = 600）;
if（gwin）
{gwin.document.open（）;
gwin.document.write（ghtml）;
var oscript = gwin.document.createElement（script）;
oscript.type =text / javascript;
oscript.src =open.js;
gwin.document.getElementsByTagName（head）[0] .appendChild（oscript）;
//gwin.document.close（）;
}
}
winopen（）;
< / script >
open.js：
function init（）{ alert（ winwin）; }
setTimeout（function（）{init（）;}， 2000 ）;
解决方案
在您的代码中，您没有显示任何应该触发脚本执行的内容。解决方案很简单：您应该将一些脚本放置为元素body或html元素的子元素。另一种方法是将属性onload添加到< body>元素中（例如，参见https://developer.mozilla.org/en-US/docs/Web/HTML/Element/body [ ^ ] ）。由于您没有显示您创建的窗口的HTML内容，我不确定您是否尝试这样做，很可能不会。

I am opening a new window using javascript and write content to the new window. Part of the content is a javascript file, but the javascript does not execute in the new window. Help?
open.html:
<script>
function winopen()
{
var ghtml = "<h1>sasaasas</h1>";
var gwin = window.open("", "_blank", "location=no,width=1000,height=600");
if (gwin)
{ gwin.document.open();
gwin.document.write(ghtml);
var oscript = gwin.document.createElement("script");
oscript.type = "text/javascript";
oscript.src = "open.js";
gwin.document.getElementsByTagName("head")[0].appendChild(oscript);
//gwin.document.close();
}
}
winopen();
</script>
open.js:
function init() { alert("winwin"); }
setTimeout(function() { init(); }, 2000); 解决方案
In your code, you did not show anything which should trigger execution of your script. The solution is simple: you should have some script placed as a child of the element "body" or your "html" element. Another approach is adding the attributeonloadto the<body>element (see, for example https://developer.mozilla.org/en-US/docs/Web/HTML/Element/body[^]). As you did not show your HTML content of your created window, I am not sure if you tried to do so, most likely not.
