How can i call a window child function in javascript?
提问by Jonathan
I am calling the parent function like window.parent.functionname();from the child page. How can i call the window.child.function()from the parent page to child page.
我正在像window.parent.functionname();从子页面一样调用父函数。如何window.child.function()从父页面调用子页面。
Any help is appreciated.
任何帮助表示赞赏。

Give your iFrame an id and try
给你的 iFrame 一个 id 并尝试
document.getElementById("iFrameId").contentWindow.functionname()
This works even when you have multiple iFrames in the same page irrespective of their order.
即使您在同一页面中有多个 iFrame，而不管它们的顺序如何，这也有效。

Do you have an iframe?
你有 iframe 吗？
Do something like that:
做这样的事情：
window.frames[0].contentDocument.functionname();

Parent page
父页面
var windowRef = null;
function openChildWindow() {
if ((windowRef != null) && (windowRef.closed == false)) {
if (windowRef.closed == false) windowRef.close();
windowRef = null;
}
var windowUrl = 'ChildPage.aspx';
var windowId = 'NewWindow_' + new Date().getTime();
var windowFeatures = 'channelmode=no,directories=no,fullscreen=no,' + 'location=no,dependent=yes,menubar=no,resizable=no,scrollbars=yes,' + 'status=no,toolbar=no,titlebar=no,' + 'left=0,top=0,width=400px,height=200px';
windowRef = window.open(windowUrl, windowId, windowFeatures);
windowRef.focus();
// Need to call on a delay to allow
// the child window to fully load...
window.setTimeout(callChildWindowFunction(), 1000);
}
function callChildWindowFunction() {
if ((windowRef != null) && (windowRef.closed == false)) windowRef.childWindowFunction();
}?
Child Page
子页面
function childWindowFunction() {
alert('Hello from childWindowFunction()');
}?

var win = null;
function openAndCall(id){
if (win!=null && win.closed==false){
win.close();
}
win = window.open("/somePage");
win.onload = function(){
win.callSome(id);
};
}
