如下的一个input
<BODY>
<input type= "text " id= "a " />
</BODY>
怎么在javascript 中给它赋值？
<script language= "javascript ">
？？？
</script>
谢谢
------解决方案--------------------
赋什么值？输入框的内容？ document.getElementById( "a ").value = ***;
------解决方案--------------------
document.getElementById( "xxx ").value;
或document.forms[0].xxx.value;
------解决方案--------------------
document.getElementById( "a ").value == " ";

<form name= "form1 " method= "post " action= " ">
<input type= "text " name= "textfield ">
<script language= "javascript ">
document.getElementById( "textfield ").value= "ssss ";
</script>
</form>
</body>
</html>
再前面html还没生成，当然找不到，或写在onload函数里面
------解决方案--------------------
<input type= "text " name= "textfield " id= "textfield "> //加个id
------解决方案--------------------
<input type= "text " name= "textfield ">
document.getElementById是取id所以id不能为空；；
