我正在做一些条件检查,并希望将某些隐藏的变量传递给请求.
例如,如果此条件通过,我想传递这些：
<script type="text/javascript">
function checkClosureLevel()
{
var openLevel = document.getElementById('openLevel');
var phyCompLevel = document.getElementById('phyCompLevel');
var finCompLevel = document.getElementById('finCompLevel');
if(openLevel.checked){
//PASS HIDDEN FORM VARIBALES HERE AND SUBMIT FORM
}
}
</script>
<form action="process.det_details" method="post" name="detParameterForm">
<fieldset class="det">
<legend>Closure Level</legend>
<input type="checkBox" name="openLevel" >Open</input><br/>
<input type="checkBox" name="phyCompLevel" >Physically Complete</input><br/>
<input type="checkBox" name="finCompLevel" >Financially Complete</input>
</fieldset>
解决方法
document.forms对象是所有< form>的集合.页面中的元素.它具有数字索引和命名项目.命名项目对应于每个< form>的name属性.
var theForm = document.forms['detParameterForm'];
为了使附加数据更容易,您可以创建一个为给定表单添加数据的函数.
function addHidden(theForm,key,value) {
// Create a hidden input element,and append it to the form:
var input = document.createElement('input');
input.type = 'hidden';
input.name = key;'name-as-seen-at-the-server';
input.value = value;
theForm.appendChild(input);
}
// Form reference:
var theForm = document.forms['detParameterForm'];
// Add data:
addHidden(theForm,'key-one','value');
addHidden(theForm,'another','meow');
addHidden(theForm,'foobarz','baws');
// Submit the form:
theForm.submit();
