Question

怎么把javaScript里面的东西存到input type=hidden的value中

<input type="hidden" id="district" name="district" value="document.getElementById('district0').value" />这样写行不我想要把不是form里面的内容以隐藏的方式传到form中

Answer 1

肯定不行
value属性不能执行脚本的
<form>
<input type="hidden" id="district" name="district" value="" />
</form>
<script type="text/javascript">
document.getElementById('district0').value="隐藏内容";
</script>

Answer 2

<input type="hidden" id="district" value="这是我" />

<form>
<input id="me" type="text" />
</form>
<script>
document.getElementByID('me').value=document.getElementByID('district').value;
</script>

Answer 3

你在district0控件上写上属性 onchange="document.getElementById('district').value=this.value" hidden里面就什么都不用写了

<input type="hidden" id="district" name="district" value="" />

Answer 4

大多数用id方式获取
<input type="text" name="" id='id'>
<script>
document.getElementById(‘id ’).value
</script>

Answer 5

<input type="hidden" id="district" name="district" value="" />
<script type="text/javascript">
document.getElementById("district").value="隐藏内容"；
</script>
