如何使用按钮 onchange 事件 运行 选定按钮的 onclick 函数?

How can I use a button onchange event to run the selected button's onclick function?

当 HTML 表单中的单选按钮被选中时,我希望它将 运行 我链接到它的 onclick 函数。我之前尝试使用 onclick 而不是 onchange,但它不适用于单选按钮。有没有人有任何 advice/tips 我可以用来解决这个问题?

function select(id, job, salary, someBool) {
  console.log(id, job, salary, someBool);
}
<form class="choice">
  <input type="radio" id="librarian" name="profession" value="lib" onclick="select('#professionSelect', 'Librarian', 4850, true);">
  <label for="librarian">Librarian: ,850/month</label><br>
  <input type="radio" id="mechanic" name="profession" value="mech" onclick="select('#professionSelect', 'Motorcycle Mechanic', 2800, true)">
  <label for="mechanic">Motorcycle Mechanic: ,800/month</label><br>
  <input type="radio" id="actor" name="profession" value="act" onclick="select('#professionSelect', 'Actor', 3100, true)">
  <label for="actor">Actor: ,100/month</label><br>
  <input type="radio" id="teacher" name="profession" value="tea" onclick="select('#professionSelect', 'Teacher', 4500, true)">
  <label for="teacher">Teacher: ,500/month</label><br>
  <input type="radio" id="doctor" name="profession" value="doc" onclick="select('#professionSelect', 'Doctor', 13000, true)">
  <label for="doctor">Doctor: ,000/month</label><br>
  <input type="radio" id="fire" name="profession" value="fi" onclick="select('#professionSelect', 'Firefighter', 3700, true)">
  <label for="fire">Firefighter: ,700/month</label><br>
  <input type="radio" id="engineer" name="profession" value="engi" onclick="select('#professionSelect', 'Computer Engineer', 9400, true)">
  <label for="engineer">Computer Engineer: ,400/month</label><br>
</form>

这样的东西行得通吗?

    $(".choice").change(function() {
        $(this).onclick();
    });

我刚刚发现您基本上是在尝试从 HTML 本身传递数据。

因此,最好的方法是使用 data- 属性 属性 来执行此操作并设置您的值并在 Javascript 中处理其余部分,而不是自己编写点击事件.

const professions = document.querySelectorAll("input[name='profession']");

function select(id, job, salary, someBool) {
  console.log(id, job, salary, someBool);
}


professions.forEach((profession)=>{  
  profession.addEventListener('click',(e)=>{
    const professionData = profession.getAttribute('data-profession');
  const dataArray = professionData.split(",");
  
  select(profession.id,dataArray[1],dataArray[2],dataArray[3]);
  })

});
<form class="choice">
  <input type="radio" id="librarian" name="profession" value="lib" data-profession="'#professionSelect', 'Librarian', 4850, true">
  <label for="librarian">Librarian: ,850/month</label><br>
  <input type="radio" id="mechanic" name="profession" value="mech" data-profession="'#professionSelect', 'Motorcycle Mechanic', 2800, true">
  <label for="mechanic">Motorcycle Mechanic: ,800/month</label><br>
  <input type="radio" id="actor" name="profession" value="act" data-profession = "'#professionSelect', 'Actor', 3100, true">
  <label for="actor">Actor: ,100/month</label><br>
</form>

试试这个代码。要了解有关数据属性的更多信息,您可以使用此 w3school 资源。

您需要使用名称属性在每个单独的无线电元素上使用 change 事件。这是您如何执行此操作的基本示例:

$('input:radio[name=profession]').change(function(el) {
        select(this.getAttribute("id"), this.getAttribute("salary"));
 });

function select(profession, salary) {
    console.log(profession + ", " + salary)
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form class="choice">
  <input type="radio" id="librarian" name="profession" value="lib" salary="4850">
  <label for="librarian">Librarian: ,850/month</label><br>
  <input type="radio" id="mechanic" name="profession" value="mech" salary="2800">
  <label for="mechanic">Motorcycle Mechanic: ,800/month</label><br>
  <input type="radio" id="actor" name="profession" value="act" salary="3100">
  <label for="actor">Actor: ,100/month</label><br>
  <input type="radio" id="teacher" name="profession" value="tea" salary="4500">
  <label for="teacher">Teacher: ,500/month</label><br>
  <input type="radio" id="doctor" name="profession" value="doc" salary="13000">
  <label for="doctor">Doctor: ,000/month</label><br>
  <input type="radio" id="fire" name="profession" value="fi" salary="3700">
  <label for="fire">Firefighter: ,700/month</label><br>
  <input type="radio" id="engineer" name="profession" value="engi" salary="9400">
  <label for="engineer">Computer Engineer: ,400/month</label><br>
</form>

select 似乎是您不能在 HTML 内联事件侦听器中使用的词。使用任何其他有效的非保留关键字。

此外,onclickonchange 属性都应该在这里起作用。这是同时使用它们的示例:

function boo(name,salary){
console.log(name,salary);
}
function body(name,salary){
console.log(name,salary);
}
function select(name,salary){
console.log(name,salary);
}
<form class="choice">
<input type="radio" id="librarian" name="profession" value="lib" onchange="body('lib',4850)">
  <label for="librarian">Librarian: ,850/month</label><br>
  <input type="radio" id="mechanic" name="profession" value="mech" onchange="select('mechanic',2800)">
  <label for="mechanic">Motorcycle Mechanic: ,800/month</label><br>
  <input type="radio" id="actor" name="profession" value="act" onchange="boo('actor',3100)">
  <label for="actor">Actor: ,100/month</label><br>
  <input type="radio" id="teacher" name="profession" value="tea" onchange="boo('teacher',4500)">
  <label for="teacher">Teacher: ,500/month</label><br>
  <input type="radio" id="doctor" name="profession" value="doc" onclick="boo('doctor',13000)">
  <label for="doctor">Doctor: ,000/month</label><br>
</form>

在上面的例子中我同时使用了selectbody,它们都不是JS中的关键字。但在内联事件处理程序中不起作用。

不过你可以直接在JS中使用它们,如下所示:

let select = function(){
  console.log(event.target.value);
}
let body = function(){
  console.log(event.target.value);
}
document.querySelector('#librarian').onchange = select;
document.querySelector('#librarian2').onchange = body;
<input type="radio" id="librarian" name="profession" value="lib"  />
  <label for="librarian">Librarian: ,850/month</label>
    <input type="radio" id="librarian2" name="profession" value="lib2"  />
  <label for="librarian2">Librarian2: ,850/month</label>

可能,为什么文档建议不要使用 inline event handlers

让你的 JS 和 HTML 分开。

一种方法:

const 
  myForm = document.forms['choice']
, data =
  { lib  : { id: '#professionSelect', job: 'Librarian',           salary:  4850, someBool: true }
  , mech : { id: '#professionSelect', job: 'Motorcycle Mechanic', salary:  2800, someBool: true }
  , act  : { id: '#professionSelect', job: 'Actor',               salary:  3100, someBool: true }
  , tea  : { id: '#professionSelect', job: 'Teacher',             salary:   500, someBool: true }
  , doc  : { id: '#professionSelect', job: 'Doctor',              salary: 13000, someBool: true }
  , fi   : { id: '#professionSelect', job: 'Firefighter',         salary:  3700, someBool: true }
  , engi : { id: '#professionSelect', job: 'Computer Engineer',   salary:  9400, someBool: true }
  }
myForm.oninput = e =>
  {
  console.clear()
  console.log( data[myForm.profession.value] )
  }
label {
  display : block;
  float   : left;
  clear   : left;
  margin  : .3em 1em;
  }
<form name="choice" >
  <label> <input type="radio" name="profession" value="lib"  > Librarian: ,850/month            </label>
  <label> <input type="radio" name="profession" value="mech" > Motorcycle Mechanic: ,800/month  </label>
  <label> <input type="radio" name="profession" value="act"  > Actor: ,100/month                </label>
  <label> <input type="radio" name="profession" value="tea"  > Teacher: ,500/month              </label>
  <label> <input type="radio" name="profession" value="doc"  > Doctor: ,000/month              </label>
  <label> <input type="radio" name="profession" value="fi"   > Firefighter: ,700/month          </label>
  <label> <input type="radio" name="profession" value="engi" > Computer Engineer: ,400/month    </label>
</form>
