关于火狐的一些问题，求大神解答

小白我现在在调一个文本编辑器eWebEditor（只支持IE内核）的兼容性，由于javascript基础差，已经调试了两周了，涉及到一些问题要请教下大神，问题如下：eWebEditor是一个iframe就是编辑区，执行eWebEditor.contentWindow.document.execCommand('InsertHtml','',html);其中html是字符串就是html语句<IMG id=LISTFO_1 title=detail dataFld=ListTable
src="http://localhost:8080/base/common/img/buttonimage/standard/tablecellprop.gif" tblMemo='{"cols":[{"fieldName":"控件
二","fieldType":"2","fieldLength":"50","fieldDefault":"field02","fieldTitle":"","fieldStyle":"","showType":"TEXT","showWidth":"","showAlign":"left","
otherInfo":{"list":"","relation":"","awoke":""},"listTableName":"detail"},{"fieldName":"控件
三","fieldType":"2","fieldLength":"50","fieldDefault":"field03","fieldTitle":"","fieldStyle":"","showType":"TEXT","showWidth":"","showAlign":"left","
otherInfo":{"list":"","relation":"","awoke":""},"listTableName":"detail"}]}' rowHeight="">
当中tblMemo='{"cols":[{"fieldName":"控件二"……这里不知道是不是现在的w3c标准还是什么，属性tblMemo=''强制转为双引号了，而里面的双引号则转为&quot;就是这样tblmemo="{&quot;cols&quot;:[{&quot;fieldName&quot;:&quot;控件二&quot，请问有什么办法不让它专过来，还有一点就是属性都强制小写了，例如dataFld会变成datafld
