Summary of jQuery Operating js Function in iframe

In this paper, an example is given to describe the method of jQuery operating js function in iframe. Share it for your reference, as follows:

1. jquery manipulates elements in iframe (2 ways)

var tha = $(window.frames["core_content"].document).find("#trewuuu").html();
var thb = $("#core_content").contents().find("#trewuuu").html();

2. Operate the elements in the parent interface (header: id for an element)

$('#header', parent.document).text()

3. js calls js function in iframe (2 kinds)

window.frames["core_content"].window.testIframe2("11");
document.getElementById("core_content").contentWindow.testIframe2("11");

4. jquery calls the js function of iframe (there will be a return value with parameters)

$("#core_content")[0].contentWindow.testIframe2("11");

Precautions:

To be in the same domain name as the included iframe (because it cannot be cross-domain)
