js parent opener top

iframe中js的加载顺序要晚于主页面中js的加载

window  parent  opener   top：

console.log(window);

console.log(window.parent);

console.log(window.top);

console.log(window.opener);

1、主页面中嵌入iframe1，iframe1点击跳转到iframe2

主页面：

Window file:///e:/daima/interchange/makeArray.html

Window file:///e:/daima/interchange/makeArray.html

Window file:///e:/daima/interchange/makeArray.html

null

 

iframe1:

Window file:///e:/daima/interchange/makeArray1.html

Window file:///e:/daima/interchange/makeArray.html

Window file:///e:/daima/interchange/makeArray.html

null

 

iframe2:

Window file:///e:/daima/interchange/makeArray2.html

Window file:///e:/daima/interchange/makeArray.html

Window file:///e:/daima/interchange/makeArray.html

null

2、主页面window.open(iframe),点击iframe1中按钮跳转到iframe2

主页面：

Window file:///e:/daima/interchange/makeArray.html

Window file:///e:/daima/interchange/makeArray.html

Window file:///e:/daima/interchange/makeArray.html

null

iframe1:

Window file:///e:/daima/interchange/makeArray1.html

Window file:///e:/daima/interchange/makeArray1.html

3:超链接和window.location.href两种方式页面跳转，两个页面相互独立，没有父子页面的关系
