如何在函数中传递一个对象的名字，然后对其进行操作？

[zhourongbiao]

例如网页中有textarea，名字叫ttt
单击某个button时，调用 fun(ttt)
然后想控制textarea的显隐，如何写代码？

[wuyg719]

document.getElementsByName('ttt')[0].style.display="none";

[wuyg719]

function fun(name){
document.getElementsByName(name)[0].style.display="none";
}

then call
fun('ttt');

[mingxuan3000]

function funct(a){
alert(a);
document.getElementsByName(a)[0].style.display="none";

}
function funct2(a){
alert(a);
document.getElementsByName(a)[0].style.display="";

}



<input type="text" name="txt111">
<input type="button" name="btn1" value="aaa" onclick="funct('txt111')">
<input type="button" name="btn2" value="bbb" onclick="funct2('txt111')">

<FORM METHOD=POST ACTION="">
<TEXTAREA NAME="ttt" ROWS="" COLS=""></TEXTAREA><br>
<input type="button" name="button" value="hid" onclick="fun(this, this.form.ttt)">
</FORM>
<SCRIPT LANGUAGE="JavaScript">
<!--
function fun(s, e) {
if (e.style.display == ""){
e.style.display = "none";
s.value = "show"
} else {
e.style.display = "";
s.value = "hid"
}
}
//-->
</SCRIPT>

简单版的：

<FORM METHOD=POST ACTION="">
<TEXTAREA NAME="ttt" ROWS="" COLS=""></TEXTAREA><br>
<input type="button" name="button" value="show and hidden" onclick="fun(this.form.ttt)">
</FORM>
<SCRIPT LANGUAGE="JavaScript">
<!--
function fun(e) {
e.style.display = e.style.display == "" ? "none" : "";
}
//-->
</SCRIPT>
