javascript - 无法让自定义下拉菜单在 QuillJS 编辑器中工作

Question

描述:我在 Quill Editor 工具栏中创建下拉列表时遇到问题。任何帮助，将不胜感激。理想情况下，我希望下拉列表显示在工具栏中，并将选择选项文本添加为​​编辑器中的文本。

HTML

<div id="editor-toolbar">
  <select class="ql-emailVars">
    <option value="1">Account Url</option>
    <option value="2">First Name</option>
    <option value="3">Login</option>
    <option value="4">Org Name</option>
    <option value="5">Support Email</option>
  </select>
</div>
<div id="editor"></div>
<div class="text-output"></div>
<div class="html-output"></div>

JS

const quill = new Quill('#editor', {
  modules: {
    toolbar: {
      container: "#editor-toolbar",
        handlers: {
          "emailVars": emailVars
        }
    }
  },
  theme: 'snow'
});

// Add Custom Dropdown to Toolbar
function emailVars(args) {
  const value = args[0];
  const cursorPosition = this.quill.getSelection().index
  this.quill.insertText(cursorPosition, value)
  this.quill.setSelection(cursorPosition + value.length)
}

谢谢，

我必须添加一些 CSS 来将其显示在工具栏上，并添加一些 JS 来将其插入到文本编辑器中。

CSS

.ql-picker.ql-emailVars {
  width: 120px;
}

.ql-picker.ql-emailVars .ql-picker-item::before, 
.ql-picker.ql-emailVars .ql-picker-label::before {
  content: 'Custom'
}

.ql-picker.ql-emailVars [data-value="1"]::before {
  content: 'Account Url'
}

.ql-picker.ql-emailVars [data-value="2"]::before {
  content: 'First Name'
}

.ql-picker.ql-emailVars [data-value="3"]::before {
  content: 'Login'
}

.ql-picker.ql-emailVars [data-value="4"]::before {
  content: 'Org Name'
}

.ql-picker.ql-emailVars [data-value="5"]::before {
  content: 'Support Email'
}

JS

const quill = new Quill('#editor', {
  modules: {
    toolbar: {
      container: "#editor-toolbar",
      handlers: {
        "emailVars": emailVars
      }
    }
  },
  theme: 'snow'
});

// Add Custom Dropdown to Toolbar
function emailVars(args) {
  const value = args[0]
  const cursorPosition = this.quill.getSelection().index
  if (value == 1) {
    this.quill.insertText(cursorPosition, "{AccountURL}")
  } else if (value == 2) {
    this.quill.insertText(cursorPosition, "{FirstName}")
  } else if (value == 3) {
    this.quill.insertText(cursorPosition, "{Login}")
  } else if (value == 4) {
    this.quill.insertText(cursorPosition, "{OrganizationName}")
  } else if (value == 5) {
    this.quill.insertText(cursorPosition, "{SupportEmail}")
  } else {
    this.quill.insertText(cursorPosition, "Please add an email variable.")
  }

  this.quill.setSelection(cursorPosition + value.length)
}
