webdriver 处理富文本框疑问

初学selenium，遇到往富文本框写入内容的疑问，在浏览器console中写入文本能成功，程序中报错写入代码为
String s = "document.getElementById('ueditor_0').contentWindow.document.body.innerText='test';";
((JavascriptExecutor)driver).executeScript(s);
报错信息为

浏览器console能写进内容
document.getElementById('ueditor_0').contentWindow.document.body.innerText='test';

"test"

请把问题写的明确点~~

    是哪个地方不明确呢？用JS往富文本框写内容，JS代码：
document.getElementById('ueditor_0').contentWindow.document.body.innerText='test';在浏览器console中能写进去，
但是代码中：
String s = "document.getElementById('ueditor_0').contentWindow.document.body.innerText='test';";
((JavascriptExecutor)driver).executeScript(s);报错

需要选定 iframe driver.switchTo().frame(XXX)方法

选定iframe啥意思呢，就是进入iframe吗，这个肯定是进入了的driver.switchTo().frame("ueditor_0");

Ellajiang 发表于 2014-8-14 16:30:13

纠结了这么久的问题，其实原因是刚刚开始已经进入iframe了，driver.switchTo().frame("ueditor_0");js里面又进入了一次，导致后面报contentWindow为空，js直接往body写内容就是了((JavascriptExecutor)driver).executeScript("document.body.innerText='spanish';");
都怪自己对js不熟悉，根本想不到，让开发看，一会儿就找到问题了
