iframe之局部刷新reload加载内容

标签：

Java JQuery JavaScript

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

方案二:用iframe的id属性定位
<input type="button" name="Button" value="Button" onclick="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" onclick="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").class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original=""来进行iframe得重定向；

示例代码如下：test.html
