Call the JS method of the child page in the parent page_javascript skills
May 16, 2016 pm 05:21 PMAfter working on it all day today, I finally found a solution online
Note: The problem is the method of calling the child page on the parent page. . . . .
Parent page: parent.html
<!DOCTYPE html PUBLIC "-//W3C/ /DTD .org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>parent</title>
<script>
function parentFunction() {
alert('function in parent');
}
function callChild() {
child.window.childFunction();
/*
child is the name attribute value of the iframe,
cannot be the id, because the id cannot be obtained from the iframe under FireFox Object
*/
}
</script>
</head>
<body>
<input type="button" name="call child" value="call child" onclick="callChild()"/>
<br/><br/>
<iframe name="child" src="./child.html "></iframe>
</body>
</html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>child</title>
<script>
function childFunction() {
alert('function in child');
}
function callParent() { parent.parentFunction();
}
</script>
</head>
<body>
<input type="button" name="call parent" value="call parent" onclick="callParent()"/>
</body>
</html>
You can modify the corresponding code according to your own needs. . . . . . .
