[英]how to get child of div element
<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>
如何獲取div中所有輸入的值以及如何在in(col1或col2)中檢查哪個div輸入;
在我的情況下,類“行”的div將通過firebase數據庫添加。
const inputs = document.querySelectorAll(".div > .col");
alert(inputs.value);
使用JavaScript,嘗試使用forEach
循環
var inputElem = document.querySelectorAll(".row input");
inputElem.forEach(function(obj){
console.log(obj.value)
})
片段:
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>
我認為這可能有效:
$("div input").each(function(){
// Get the value:
console.log($(this).val());
// check in which div input in(col1 or col2)
console.log($(this).closest("div").attr("class"));
});
嘗試這個:
const inputs = document.getElementById('div').getElementsByTagName('input');
console.log(inputs[0].value, inputs[1].value);
