jquery string to dom object
In front-end development, we often need to operate DOM objects, and sometimes we need to convert strings into DOM objects. The jQuery framework provides us with a very convenient way to achieve this requirement.
The following is an example. There is a button and a div element in the HTML document. We can click the button to convert the string in the input box into a new div element and add it to the page.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>jQuery字符串转DOM对象</title>
<style>
#container {
width: 200px;
height: 200px;
border: 1px solid black;
margin: 50px auto;
text-align: center;
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
}
</style>
</head>
<body>
<div id="container">
<button id="btn">添加元素</button>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("#btn").on("click", function() {
var inputStr = prompt("请输入字符串：");
var newDiv = $("<div></div>").text(inputStr); // 将字符串转换为DOM对象
$("#container").append(newDiv); // 添加新的div元素
})
})
</script>
</body>
</html>We use the jQuery method$("<div></div>")Create a new div object, and then use .text(inputStr)Use the string in the input box as the content of the new div element. Add a new div element to the #container via .append(newDiv).
Using jQuery can easily convert strings into DOM objects, which greatly simplifies our work.
