需要在iframe中从父级清除clearInterval，但无法正常工作 [英] Need to clearInterval in iframe from parent and it's not working

问题描述

我正在iframe中使用setInterval，我需要能够从父窗口中将其停止，并且它似乎无法正常工作.我正在为要从父级访问的setInterval事件分配一个全局变量('modelViewRefresh').

I'm using setInterval inside an iframe, and I need to be able to stop it from the parent window, and it doesn't seem to be working. I'm assigning a global variable ('modelViewRefresh') to the setInterval event to be accessed from the parent.

我在父级中使用此代码来尝试触发clearInterval，但似乎不起作用:

I'm using this code in the parent to try and trigger clearInterval, but it doesn't seem to be working:

var modelViewRefresh = document.getElementById(widget_id + '_iframe').contentWindow['modelViewRefresh'];
console.log("modelViewRefresh=" + modelViewRefresh); // this equals 2 for some reason
clearInterval( modelViewRefresh );

我什至直接尝试这样做:

I'm even trying this directly:

clearInterval( document.getElementById(widget_id + '_iframe').contentWindow['modelViewRefresh'] );

我已经在自己的窗口中打开了iframe，以验证是否正在创建变量(通过Firebug在DOM中查找).仅供参考，这不是一个不同的域...

I've opened the iframe in a window of its own to verify that the variable is being created (by looking in the DOM via Firebug). FYI it's not a different domain...

我主要在其他地方使用jQuery，但在某处阅读，最好在这种情况下使用原始" JavaScript.因此，我也欢迎使用jQuery解决方案.

I'm mainly using jQuery elsewhere, but read somewhere that it's best to use 'raw' javascript in this instance. So I'm open to a jQuery solution too.

有什么想法吗?也许我正在做错事情...

Any ideas? Maybe I am going about it wrong...

PS.我还希望能够再次从父母那里开始刷新".

PS. I'd also like to be able to start the 'refresh' again from the parent.

推荐答案

从外部调用时， clearInterval 和 clearTimeout 都需要 iframe名称iframe.

Both clearInterval and clearTimeout require the iframe name when called from outside the iframe.

HTML示例:< iframe名称="iframe_0"></iframe>

JS示例:

iframe_0.clearInterval(modelViewRefresh)

要从父级重新启动: modelViewRefresh = iframe_0.setInterval(do_this，1000)
