    <form><input type="button" name="bt_submit" class="pollButtonNormal" onmouseover="this.className='pollButtonHigh';" onmouseout="this.className='pollButtonNormal';" value="Resultaten" onclick="javascript:viewResults1();" style="padding-bottom: 3px; margin-top: 10px; "></form>
</div>

在我的剧本中我有：

var r = document.forms.pollvoteform1.poll_option1;

但我收到错误：

document.forms.pollvoteform1未定义我不明白为什么。由于pollvoteform1和poll_option_1都在那里。

// update：完整的js代码

    function vote() {
var r=document.forms.pollvoteform1.poll_option1;
var voted=false;
if (r.value!=null && r.checked){
voted=true;
} else {
for (i=0;i<r.length;i++){
if (r[i].checked) {
voted=true;
break;
}
}}

if (voted) {
document.forms.pollvoteform1.submit();
} else {
alert("you didn't make a choice yet");
}
}

Answer 1

要么是

var r=document.forms['pollvoteform1'].poll_option1;

或者如果不起作用

var r=document.forms[0].poll_option1;

Answer 2

尝试在表单中添加ID标记。它应该与名称标签相同。

Answer 3

您的代码在IE7和Firefox 3.0.10中运行良好。

您使用的是哪种浏览器？

js似乎无法找到我的表格
