html编辑器浏览器兼容问题
在学做一个HTML编辑器。。在浏览器兼容方面发现很多不同。。。
js 代码：window.onload=function()
{
var leleHTML = document.getElementById("leleEditor").contentWindow;
leleHTML.document.designMode = "on";
leleHTML.document.contentEditable = true;
leleHTML.focus();
}
function CheckForm()
{
var leleContent = document.getElementById("leleEditor").contentWindow.document.getElementsByTagName("body")[0].innerHTML
var leleHTML = document.getElementById("leleEditor").contentWindow;
if(leleContent==""||leleContent=="<P> </P>"||leleContent=="<br>")
{
alert("请输入内容，谢谢！");
leleHTML.focus();
return false;
}
else
{
getValue(leleContent);
}
}
function getValue(content)
{
document.getElementById("content").value=content; //此处需要根据表单名字进行变换
}
//字体选择
function FontName(value)
{
var leleHTML = document.getElementById("leleEditor").contentWindow;
var leleText = leleHTML.document.selection.createRange();
if(leleText)
{
leleHTML.document.execCommand("FontName", "false", value);
}
}
//文字大小
function FontSize(value)
{
var leleHTML = document.getElementById("leleEditor").contentWindow;
var leleText = leleHTML.document.selection.createRange();
if(leleText)
{
leleHTML.document.execCommand("FontSize", "false", value);
}
}
