Question

对于下面的代码，我必须使用4个函数来显示4个输入字段的值。

＆＃13;

FD_CLOEXEC

＆＃13;

有没有办法只用一个函数来做同样的工作？

Answer 1

尝试这个

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>

Your input:
<p id="demo"></p>

Answer 2

你可以这样做：

'../_mocks_/utilities'

Answer 3

<!DOCTYPE html>
<html>
<body>

Name: <input type="text" id="name1" value="" onBlur="myFunction(this)"><br>
Age: <input type="number" id="age1" value="" onBlur="myFunction(this)"><br>
Job: <input type="text" id="job1" value="" onBlur="myFunction(this)"> <br>
Tel: <input type="text" id="tel1" value="" onBlur="myFunction(this)"> <br> 

<p>Type then click outside to display the value of the input field.</p>

Your input:
<p id="demo"></p>

<script>
function myFunction(arg) {

    var id = arg.getAttribute('id');
    var x = document.getElementById(id).value;

     document.getElementById("demo").innerHTML = x;
}

</script>

</body>
</html>

Answer 4

＆＃13;

merge into table_a a
using table_b b
on (a.id = b.id)
when matched then
  update set a.salary = b.salary
when not matched then
  insert (id, salary) values (b.id, b.salary);

＆＃13;

function myFunction(val) {
  document.getElementById("demo").innerHTML = val;
}

＆＃13;

Answer 5

将参数传递给函数。

<body>

Name: <input type="text" id="name1" value="" onBlur="myFunction1(this.value)"><br>
Age: <input type="number" id="age1" value="" onBlur="myFunction1(this.value)"><br>


<p>Type then click outside to display the value of the input field.</p>

Your input:
<p id="demo"></p>

<script>
function myFunction1(val) {

    document.getElementById("demo").innerHTML = val;

}

</script>

但我认为你需要的就是这个。

Name: <input type="text" id="name1" value="" onBlur="myFunction1(this.value)"><br>
Age: <input type="number" id="age1" value="" onBlur="myFunction2(this.value)"><br>


<p>Type then click outside to display the value of the input field.</p>

Name Your input:
<p id="demo"></p>

Age Your input:
<p id="demo1"></p>

<script>
function myFunction1(val) {

    document.getElementById("demo").innerHTML = val;

}

function myFunction2(val) {

    document.getElementById("demo1").innerHTML = val;

}

</script>

单一函数捕获不同输入域的不同值
