我有一个html文件,我想获取使用javascript在输入字段中输入的文本。我尝试了几种不同的方法,但似乎没有任何工作正常。这是我现在拥有的代码。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<title>Document</title>
</head>
<body>
<input type="text" id="searchingterm">
<form>
<input type="text" id="search">
</form>
<script>
$(document).ready(function(){
var searched = document.getElementById("search").value;
console.log(searched)
})
</script>
</body>
</html>
我也尝试过使用jquery,但这也没有做任何事情。

基本上,问题在于您没有为该输入分配任何内容,也没有触发function search() {
var searched = document.getElementById("search").value;
console.log(searched)
}
的功能。
您的代码是正确的,您只需要稍作更改即可。
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

</head>
<body>
<form>
<input type="text" id="search">
</form>
<button onclick="search()"> search</button>
</body>
</html>
body
此处在<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<title>Document</title>
</head>
<body>
<form>
<input type="text" id="search">
</form>
<button onclick="search()"> search</button>
<script>
function search() {
var searched = document.getElementById("search").value;
console.log(searched)
}
</script>
</body>
</html>
