如何获得div元素的孩子

Question

<div class="div" id="div">
    <div class="row">
        <div class="col1">
             <input type="text">
             <!--I need to get a value of these inputs-->
        </div>
        <div class="col2">
             <input type="text">
             <!--I need to get a value of these inputs-->
        </div>
    </div>
    <div class="row">
        <div class="col1">
             <input type="text">
             <!--I need to get a value of these inputs-->
        </div>
        <div class="col2">
             <input type="text">
             <!--I need to get a value of these inputs-->
        </div>
    </div>
</div>

如何获取div中所有输入的值以及如何检入（col1或col2）中的div输入;

在我的情况下，带有“row”类的div将通过firebase数据库添加。

const inputs = document.querySelectorAll(".div > .col");
alert(inputs.value);

Answer 1

使用JavaScript，尝试使用forEach

进行循环

var inputElem = document.querySelectorAll(".row input");
inputElem.forEach(function(obj){
    console.log(obj.value)
})

段：

var inputElem = document.querySelectorAll(".row input");
inputElem.forEach(function(obj){
	console.log(obj.value)
})

<div class="div" id="div">
    <div class="row">
        <div class="col1">
             <input type="text" value="one">
             <!--I need to get a value of these inputs-->
        </div>
        <div class="col2">
             <input type="text" value="two">
             <!--I need to get a value of these inputs-->
        </div>
    </div>
    <div class="row">
        <div class="col1">
             <input type="text" value="three">
             <!--I need to get a value of these inputs-->
        </div>
        <div class="col2">
             <input type="text" value="four">
             <!--I need to get a value of these inputs-->
        </div>
    </div>
</div>

Answer 2

我认为这可行：

$("div input").each(function(){
    // Get the value:
    console.log($(this).val());
    // check in which div input in(col1 or col2)
    console.log($(this).closest("div").attr("class"));
});

Answer 3

试试这个：

const inputs = document.getElementById('div').getElementsByTagName('input');
console.log(inputs[0].value, inputs[1].value);
