如果将TEXTAREA里的内容的HTML代码替换掉？

[黑马]

在TEXTAREA里的内容的HTML代码带有“ ”等符号，想把他们替换成空格，有办法吗？

[meizz]

var s = document.getElementById("txtId").value;
document.getElementById("txtId").value = s.replace(/\ \;/g, " ")

[hookee]

是指那些Entity吗？
s = document.formname.textarea.value;
s = s.replace(/ /ig," ");
s = s.replace(/</ig,"<");
s = s.replace(/>/ig,">");
s = s.replace(/"/ig,"\"");
s = s.replace(/'/ig,"\'");
s = s.replace(/&/ig,"&");

[adverse]

document.getElementById("txtId").value = document.getElementById("txtId").value.replace(/\ \;/g, " ")

[cuixiping]

with(document.getElementById("txtId"))innerHTML=value;

搞定
