iframe之局部刷新

<iframe src=”1.htm” name=”ifrmname”
id=”ifrmid”></iframe>

方案一:用iframe的name属性定位
<input type=”button” name=”Button” value=”Button” οnclick=”document.frames(‘ifrmname’).location.reload()”>
或
<input type=”button” name=”Button” value=”Button” οnclick=”document.all.ifrmname.document.location.reload()”>

方案二:用iframe的id属性定位
<input type=”button” name=”Button” value=”Button” οnclick=”ifrmid.window.location.reload()”>

方案三:当iframe的src为其它网站地址(跨域操作时)
<input type=”button” name=”Button” value=”Button” οnclick=”window.open(document.all.ifrmname.src,’ifrmname’,”)”>

方案四:通过和替换iframe的src来实现局部刷新
可以用document.getElementById(“iframname”).src=””来进行iframe得重定向；

示例代码如下：test.html

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33
