我一直在试图解决这个问题，但我自己似乎无法做到这一点。如果我对 div 的名称进行硬编码并使用单个按钮，我有一个可以工作的函数。然而，我想用大约 10 个不同的按钮来完成此操作，并让它们使用相同的功能，而不是复制该功能 10 次。这是工作代码:

document.getElementById("genderBtn").addEventListener("click", myFunction);

function myFunction() {
  var x = document.getElementById("gender");
  if (x.style.display === "none") {
    x.style.display = "block";
  } else {
    x.style.display = "none";
  }
}

/* Checkbox Lineup */

fieldset.group {
  margin: 0;
  padding: 0;
  margin-bottom: 1.25em;
  padding: .125em;
}

fieldset.group legend {
  margin: 0;
  padding: 0;
  font-weight: bold;
  margin-left: 20px;
  font-size: 100%;
  color: black;
}

ul.checkbox {
  margin: 0;
  padding: 0;
  margin-left: 20px;
  list-style: none;
}

ul.checkbox li input {
  margin-right: .25em;
}

ul.checkbox li {
  border: 1px transparent solid;
  display: inline-table;
  width: 12em;
}

ul.checkbox li label {
  margin-left: ;
}

ul.checkbox li:hover,
ul.checkbox li.focus {
  background-color: lightyellow;
  border: 1px gray solid;
  width: 12em;
}


/* Radio button lineup */

ul.radio {
  margin: 0;
  padding: 0;
  margin-left: 20px;
  list-style: none;
}

ul.radio li input {
  margin-right: .25em;
}

ul.radio li {
  border: 1px transparent solid;
  display: inline-table;
  width: 12em;
}

ul.radio li label {
  margin-left: ;
}

ul.radio li:hover,
ul.radio li.focus {
  background-color: lightyellow;
  border: 1px gray solid;
  width: 12em;
}

hr {
  display: block;
  height: 1px;
  border: 0;
  border-top: 1px solid #ccc;
  margin: 1em 0;
  padding: 0;
}

<fieldset class="group">
  <legend>
    <h1>Demographics <button type="button" id="genderBtn">Gender</button></h1>
  </legend>

  <ul class="checkbox">
    <li><label for="name">Name: </label><input type="text" name="" id="name" value="" placeholder="default: client" /></li>
    <li><label for="age">Age: </label><input type="text" name="" id="age" value="" /></li><br>
  </ul>
  <hr />
  <div id="gender">
    <b>Biological Sex</b>
    <ul class="checkbox">
      <li><input type="checkbox" name="gender[]" id="gender0" value="female" /><label for="gender0">Female</label></li>
      <li><input type="checkbox" name="gender[]" id="gender1" value="male" /><label for="gender1">Male</label></li><br>
    </ul>
    <hr />
  </div>
  <b>Ethnic/Racial Information</b>
  <ul class="checkbox">
    <li><input type="checkbox" name="race[]" id="race0" value="Caucasian" /><label for="race0">Caucasian</label></li>
    <li><input type="checkbox" name="race[]" id="race1" value="African-American" /><label for="race1">African-American</label></li>
    <li><input type="checkbox" name="race[]" id="race2" value="Hispanic" /><label for="race2">Hispanic</label></li>
    <li><input type="checkbox" name="race[]" id="race3" value="Arabic" /><label for="race3">Arabic</label></li>
    <li><input type="checkbox" name="race[]" id="race4" value="Asian" /><label for="race4">Asian</label></li>
    <li><input type="checkbox" name="race[]" id="race5" value="multi-racial" /><label for="race5">Multi-racial</label></li>
    <li><label for="race6">Other:</label><input type="text" name="" id="race6" value="" /></li>
  </ul>
</fieldset>

现在，当我尝试更改它以将 div 名称作为变量传递时，我似乎无法让它工作。

document.getElementById("someOtherBtn").addEventListener("click", myFunction(someOtherDiv));

function myFunction(theDivName) {
  var x = document.getElementById("theDivName");
  if (x.style.display === "none") {
    x.style.display = "block";
  } else {
    x.style.display = "none";
  }
}

有人可以让我知道我做错了什么吗？

未测试:

document.getElementById("someOtherBtn").addEventListener("click", function() {
   myFunction("someOtherDiv");
});

function myFunction(theDivName) {
  var x = document.getElementById(theDivName);
  if (x.style.display === "none") {
    x.style.display = "block";
  } else {
    x.style.display = "none";
  }
}

或者

myClickFunction("someOtherDiv");
myClickFunction("someOtherDiv2");
myClickFunction("someOtherDiv3");

function myClickFunction(theDivName) {
     var x = document.getElementById(theDivName);
     x.addEventListener("click", function() {
        myFunction(x);
     });
}
function myFunction(theDivElement) {
  var x = theDivElement;
  if (x.style.display === "none") {
    x.style.display = "block";
  } else {
    x.style.display = "none";
  }
}
