1.子页面取父页面的值
采用url 传值的方式 ?+&
<iframe src="child.html?a=1&b=2&c=3"></iframe>
这样,在子页面的js中便可以取值,将物质方法封装为一个FUNCTION
function Request(argname){ var url = document.location.href; var arrStr = url.substring(url.indexOf("?")+1).split("&"); //return arrStr; for(var i =0;i<arrStr.length;i++) { var loc = arrStr[i].indexOf(argname+"="); if(loc!=-1){ return arrStr[i].replace(argname+"=","").replace("?",""); break; } } return ""; }
这样就可以轻松取出所有的参数值
var a= Request("a");var b= Request("b");var c= Request("c");
2.子页面调用父页面的方法
子页面调用父页面方法,parent.方法名()即可。
var word = parent.say();
3.子页面向父页面传参
可以理解为在父页面定义了一个变量,子页面调用该变量并且给它赋值。
window.parent.id="123"
4.父页面调用子页面方法
<iframe name="myframe" src="child.html"></iframe>
调用方法:
myframe.window.functionName();

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
