目标页面具有简单的HTML设置:
The target page has a simple HTML setup:
<html> <body> <frameset id="mainset" rows="50%,50%"> ... </frameset> </body> </html>，我想使用JavaScript添加框架.
and I'd like to add frames using JavaScript.
这不起作用:
var parent = document.getElementsByTagName("frameset")[0]; var child = document.createElement("frame"); child.src = "about:blank"; child.style = "background-color: red;"; parent.appendChild(child);这确实有效，但是会创建一个iframe:
This does work, but it creates an iframe:
var parent = document.getElementsByTagName("body")[0]; var child = document.createElement("iframe"); child.src = "about:blank"; child.style = "background-color: red;"; parent.appendChild(child);是否可以使用javascript将框架添加到框架集中?
Is there a way to add frames to the frameset using javascript?
对不起，如果您之前曾问过这个问题.我搜索并找到了很多解决类似问题的人的解决方案"，但是这些似乎不适用于此处.
Sorry if this question has been asked before. I searched and found a lot of 'solutions' for people having similar problems, but those don't seem to apply here.
目标页面如下:
推荐答案
仅添加新的<frame>是不够的.您还必须调整包含的<frameset>的rows或cols属性.
It's not enough to add a new <frame>. You must also adjust the rows or cols attribute of the containing <frameset>.
此外，如果框架集具有id，则 使用 ，而不是尝试通过标记名获取节点. (ID快速且唯一.)
Also, if the frameset has an id, use it instead of trying to get the node by tagname. (Ids are fast and unique.)
这样的代码可以使用(暂时):
Code like this will work (for now):
您可以 在此jsBin上查看运行中的代码 .
You can see the code in action at this jsBin.
var parent = document.getElementById ("mainset"); var child = document.createElement ("frame"); child.style = "background-color: pink;"; parent.appendChild (child); parent.rows = "30%,30%,30%" var docRdyInt = null; var frmCW = child.contentWindow; if (frmCW) { //-- Must wait for the new frame to be writable, esp in Firefox. docRdyInt = setInterval (createFramedPage, 50); } else { alert ("Oopsie! may be a rendering delay in some cases. Try code from console."); } function createFramedPage () { if (frmCW.document.readyState == "complete") { clearInterval (docRdyInt); frmCW.document.body.innerHTML = '<p>Hello World!</p>'; } }更多推荐
