对于下面的代码，我必须使用 4 个函数来显示 4 个输入字段中的值。
<!DOCTYPE html>
<html>
<body>
Name: <input type="text" id="name1" value="" onBlur="myFunction1()"><br>
Age: <input type="number" id="age1" value="" onBlur="myFunction2()"><br>
Job: <input type="text" id="job1" value="" onBlur="myFunction3()"> <br>
Tel: <input type="text" id="tel1" value="" onBlur="myFunction4()"> <br>
<p>Type then click outside to display the value of the input field.</p>
Your input:
<p id="demo"></p>
<script>
function myFunction1() {
var x = document.getElementById("name1").value;
document.getElementById("demo").innerHTML = x;
}
function myFunction2() {
var y = document.getElementById("age1").value;
document.getElementById("demo").innerHTML = y;
}
function myFunction3() {
var z = document.getElementById("job1").value;
document.getElementById("demo").innerHTML = z;
}
function myFunction4() {
var a = document.getElementById("tel1").value;
document.getElementById("demo").innerHTML = a;
}
</script>
</body>
</html>有没有办法只使用 1 个函数来完成相同的工作？
最佳答案
试试这个
function myFunction1(val) {
var x = val;
document.getElementById("demo").innerHTML = x;
}Name: <input type="text" id="name1" value="" onBlur="myFunction1(this.value)"><br>
Age: <input type="number" id="age1" value="" onBlur="myFunction1(this.value)"><br>
Job: <input type="text" id="job1" value="" onBlur="myFunction1(this.value)"> <br>
Tel: <input type="text" id="tel1" value="" onBlur="myFunction1(this.value)"> <br>
<p>Type then click outside to display the value of the input field.</p>
