Getting all child input elements within a div
提问by samsu
I am trying to get all the values of the input fields. The issue is all of the <input type=radio/>are dynamic and can increase or decrease at any time.
我正在尝试获取输入字段的所有值。问题是所有这些<input type=radio/>都是动态的，可以随时增加或减少。
So I am starting with the main DI and going from there. The problem I have now is I am not getting the input radio buttons values.
所以我从主要的 DI 开始，然后从那里开始。我现在遇到的问题是我没有获得输入单选按钮值。
So here are the steps I am intending to accomplish:
所以这里是我打算完成的步骤：
- If any radio button is selected, pass its value to the checkbox value,
- If the radio button is selected and the checkbox is not selected, do notpass to the checkbox value
- 如果选择了任何单选按钮，则将其值传递给复选框值，
- 如果单选按钮被选中而复选框未被选中，则不传递给复选框值
I am looking for a solution in JavaScript only - do not use jQuery

This executes when the checkbox is clicked:
当复选框被点击时执行：
function getpref(val) {
var wr = document.getElementById(val);
childElements = wr.childNodes;
//alert(childElements);
for(var i = childElements.length-1; i>=0; i--){
var elem = childElements[i];
console.log(elem.id);
if(elem.id && elem.id.indexOf(val+'_')==0){
elem.style.display = 'block';
}
}
//alert(val);
}

You can use getElementsByNameto get you all of the radio buttons by name='deliveryMethodId'and then go from there:
您可以使用getElementsByName让您获得所有单选按钮name='deliveryMethodId'，然后从那里开始：
function getpref(val) {
var radioButtons = document.getElementById(val).getElementsByName("deliveryMethodId");
for(var i = radioButtons.length-1; i>=0; i--)
{
var radioButton = radioButtons[i];
if(radioButton.checked)
console.log(radioButton.id + " is selected ");
}
}

You can directly access input nodes in your DIV with getElementsByTagName
您可以直接访问 DIV 中的输入节点 getElementsByTagName
function getpref(val) {
var divNode = document.getElementById(val);
var inputNodes = divNode.getElementsByTagName('INPUT');
for(var i = 0; i < inputNodes.length; ++i){
var inputNode = inputNodes[i];
if(inputNode.type == 'radio') {
//Do whatever you want
if(inputNode.checked) {
//Do whatever you want
}
}
}
}
