扩展@c23gooey 的答案,这是我们针对类似问题提出的问题(插入动态生成的邮件合并占位符)。
var commandName = 'placeholders',
iconName = commandName + 'Icon',
buildListItem = function (name, value) {
// Depending on prior validation, escaping may be needed here.
return '<li><a class="fr-command" data-cmd="' + commandName +
'" data-param1="' + value + '" title="' + name + '">' +
name + '</a></li>';
};
// Define a global icon (any Font Awesome icon).
$.FroalaEditor.DefineIcon(iconName, { NAME: 'puzzle-piece' });
// Define a global dropdown button for the Froala WYSIWYG HTML editor.
$.FroalaEditor.RegisterCommand(commandName, {
title: 'Placeholders',
type: 'dropdown',
icon: iconName,
options: {},
undo: true,
focus: true,
refreshAfterCallback: true,
callback: function (cmd, val, params) {
var editorInstance = this;
editorInstance.html.insert(val);
},
refreshOnShow: function ($btn, $dropdown) {
var editorInstance = this,
list = $dropdown.find('ul.fr-dropdown-list'),
listItems = '',
placeholders = editorInstance.opts.getPlaceholders();
// access custom function added to froalaOptions on instance
// use a different iteration method if not using Angular
angular.forEach(placeholders, function (placeholder) {
listItems += buildListItem(placeholder.name, placeholder.value);
});
list.empty().append(listItems);
if (!editorInstance.selection.inEditor()) {
// Move cursor position to end.
editorInstance.selection.setAtEnd(editorInstance.$el.get(0));
editorInstance.selection.restore();
}
}
});
我们通过 Froala 支持运行了这个方法,并被告知:
编辑器在显示下拉菜单时没有任何使用动态内容的内置机制,但您的解决方案绝对是一个不错的解决方案。
