Angular ng2编辑器中的自定义函数
我正在从事Angular 4项目,并在其中使用ng2 CkEditor。我已经覆盖了CkEditor的一些按钮的基本功能,如保存和预览,以执行我自己的功能。下面是我的代码Angular ng2编辑器中的自定义函数,angular,typescript,ckeditor,Angular,Typescript,Ckeditor,我正在从事Angular 4项目,并在其中使用ng2 CkEditor。我已经覆盖了CkEditor的一些按钮的基本功能,如保存和预览,以执行我自己的功能。下面是我的代码 <ckeditor (ready)="OnReady()" [config]="editorConfig" formControlName="EditorNote" #CkEditor> <ckbutton

PreviewOfferLetter()方法如下所示--
现在,当我点击“预览”按钮时,它会在控制台中抛出一个错误,上面写着--
如果我做错了什么,请提出建议。提前感谢。您的语法正在丢失类的上下文。考虑切换到胖箭头,这样可以防止:
public OnReady() {
this.CkEditor.instance.addCommand("source", {
exec: () => {
alert("Custom handler for source button ");
}
});
this.CkEditor.instance.addCommand("preview", {
exec: () => {
this.PreviewOfferLetter()
}
});
}
您还可以使用闭包,它更难看,但也可以工作:
public OnReady() {
const self = this;
this.CkEditor.instance.addCommand("source", {
exec: function() {
alert("Custom handler for source button ");
}
});
this.CkEditor.instance.addCommand("preview", {
exec: function() {
self.PreviewOfferLetter()
}
});
}
谢谢亲爱的,这真的很有效。非常感谢:)
this.PreviewOfferLetter is not a function
public OnReady() {
this.CkEditor.instance.addCommand("source", {
exec: () => {
alert("Custom handler for source button ");
}
});
this.CkEditor.instance.addCommand("preview", {
exec: () => {
this.PreviewOfferLetter()
}
});
}
public OnReady() {
const self = this;
this.CkEditor.instance.addCommand("source", {
exec: function() {
alert("Custom handler for source button ");
}
});
this.CkEditor.instance.addCommand("preview", {
exec: function() {
self.PreviewOfferLetter()
