从另一个iframe更改iframe源代码 [英] Change iframe source from another iframe

问题描述

好的，我在父页面内有2个iframe（无论出于何种原因）。

Ok, I have 2 iframes inside a parent page (for whatever reason).

我在父页面上有一个导航菜单，它改变了iframe的来源＃ 1 ...

I have a navigation menu on parent page, which changes the source of iframe #1...

iFrame＃1的工作，是显示另一个导航菜单...就像一个子导航菜单......

iFrame #1's job, is to display ANOTHER navigation menu... Like a subnavigation menu...

现在，如何点击iFrame＃1中的li，更改iframe＃2的来源？它们都在同一个父页面上...

Now, how can I upon clicking an li inside iFrame #1, change the source of iframe #2? They're both on the same parent page...

除了惨遭失败之外，我还收到Chrome开发工具的警告 -

Aside from failing miserably, I also get a warning from Chrome's Dev tools -

不安全的JavaScript尝试使用URL文件访问框架：/// C：/website/index.html来自带有URL文件的框架：/// C：/website/news/navigator.html。域，协议和端口必须匹配。

Unsafe JavaScript attempt to access frame with URL file:///C:/website/index.html from frame with URL file:///C:/website/news/navigator.html. Domains, protocols and ports must match.

这里有一些代码可以使事情变得更加清晰：

Here's some code to make things slightly clearer:

HTML

<!-- HTML for the parent page itself -->
<iframe id="frameone" src=""></iframe>
<iframe id="frametwo" src=""></iframe>
<button onclick="onenav('test.html')">Change 1st frame</button>

<!-- The following is the HTML that is loaded inside "frameone" -->
<button onclick="twonav('test2.html')">Change 2nd frame</button>

// Javascript
var one = document.getElementById('frameone');
var two = document.getElementById('frametwo');

function onenav(x){
    one.src = x;
}

function twonav(y){
    two.src = y;
}

对我而言，这是有道理的，因为这一切都在父母身上执行page ...在加载时，我查询开发工具，我可以看到，'one'和'two'都有框架元素......第一个按钮工作，第二个按钮不工作......

To me, this makes sense, since this is all being executed on the parent page... On loading, I query the dev tools and I can see that both, 'one' and 'two' have frame elements... The first button works, the second one, doesn't...

推荐答案

使用parent.twonav时适用于我

Works for me when using parent.twonav

DEMO

var links = [
    'javascript:\'<button onclick="parent.twonav(1)">Change 2nd frame</button>\'',
    'javascript:\'Hello\''
];
var one, two;
window.onload=function() {
  one = document.getElementById('frameone');
  two = document.getElementById('frametwo');
}  

function onenav(idx) {
    one.src=links[idx];
}  

function twonav(idx) {
    two.src=links[idx];
}
