Knockout.js 如何在使用knockout时设置每个实例的ckeditor高度?
我将ckeditor与knockout.js一起使用,似乎无法为每个实例设置编辑器的实例。 这是我的密码:Knockout.js 如何在使用knockout时设置每个实例的ckeditor高度?,knockout.js,ckeditor,Knockout.js,Ckeditor,我将ckeditor与knockout.js一起使用,似乎无法为每个实例设置编辑器的实例。 这是我的密码: ko.bindingHandlers.CKEDITOR = { init: function (element, valueAccessor, allBindings, viewModel, bindingContext) { // This will be called when the binding is first applied to an element //
ko.bindingHandlers.CKEDITOR = {
init: function (element, valueAccessor, allBindings, viewModel, bindingContext) {
// This will be called when the binding is first applied to an element
// Set up any initial state, event handlers, etc. here
var ckEditorValue = valueAccessor();
var id = $(element).attr('id');
var options = allBindings().EditorOptions;
var instance = CKEDITOR.replace(id, {
on: {
change: function () {
ckEditorValue(instance.getData());
}
},
height: 350 // doesn't set the height...
})
}
})
我可以在init函数中使用以下代码:
CKEDITOR.on('instanceReady', function () {
if (typeof (options) != 'undefined') {
viewModel.css({ 'width': options.Width });
viewModel.find('.cke_contents').css({ 'height': options.Height });
}
});
但对于每个实例,这是调用的两倍。。。因此,我需要对每个实例更加关注。
有可能吗?我设法这样解决了这个问题: 首先,我为html中的每个编辑器设置了一个选项绑定,如下所示:
<textarea data-bind="CKEDITOR: Content, id: '1', EditorOptions: { height: 250, width: 670 }"></textarea>
<textarea id="2" data-bind="CKEDITOR: Content, EditorOptions: { height: 100 }"></textarea>
没有有效的例子很难判断。您的高度:350实例定义。调试时,我可以看到它将高度设置为350,然后使用内联样式覆盖它。
ko.bindingHandlers.CKEDITOR = {
init: function (element, valueAccessor, allBindings, viewModel, bindingContext) {
var ckEditorValue = valueAccessor();
var id = $(element).attr('id');
var allBindings = allBindings();
// this holds the height for each instance
var options = allBindings.EditorOptions;
id = (typeof allBindings.id == 'undefined' ? id : allBindings.id);
$(element).attr('id', id);
var ignoreChanges = false;
var defaultConfig = {};
defaultConfig.toolbar = [
["Undo", "Redo"],
["Bold", "Italic", "Underline", "Strike", "RemoveFormat", "-", "TextColor"],
["NumberedList", "BulletedList", "Outdent", "Indent"],
["JustifyLeft", "JustifyCenter", "JustifyRight", "JustifyBlock"],
["Link", "Unlink"]
];
defaultConfig.defaultLanguage = 'en';
defaultConfig.removePlugins = 'resize, wordcount, elementspath, magicline';
defaultConfig.enterMode = CKEDITOR.ENTER_BR;
defaultConfig.on = {
change: function () {
ignoreChanges = true;
ckEditorValue(instance.getData());
ignoreChanges = false;
}
};
// merge the height with the defaultConfig
$.extend(defaultConfig, options);
var instance = CKEDITOR.replace(id, defaultConfig);
instance.setData(ckEditorValue());
ckEditorValue.subscribe(function (newValue) {
if (!ignoreChanges) {
instance.setData(newValue);
}
});
}
};
