在javascript中是否有任何事件只能通过脚本而不是指针或键操作触发？ [英] Is there any event in javascript which can only be fired through a script and not by pointer or key actions?

问题描述

我必须在点击Reactive-table中的一个列时将数据上下文传递给表行，找不到这样做，我想知道是否有任何我可以触发的事件我的代码在行上，但用户不能在没有代码访问的情况下执行此操作。

I have to get the data context passed to a table row on clicking on one of its columns in a "Reactive-table", finding no way to do this, I am wondering if there is any event which I can fire in my code on the row, but the user should not be able to do this without the code access.

推荐答案

点击任意在tr的tds中，我将事件冒泡到它的行，向获取的元素添加一个类，然后在该行上触发click（）事件，单击后我从tr中删除添加的类。

On click of any of the tds of a tr, I bubble the event to its row, add a class to the obtained element, then fire a click() event on that row, After click I remove the added class from the tr.

"click td": function(event) {
    event.stopPropagation();
    var tr = Utils.bubbleTo(event.target, "tr");
    $(tr).addClass("customClass");
    $(tr).click();
    $(tr).removeClass("customClass");
    //used the row data using, Template.instance().dict.get("data"),which is set in the next method.
},

"click .reactive-table tbody tr.customClass": function clickTr() {
    Template.instance().dict.set("data", this);
},

我想要一个只能通过脚本触发的事件的原因是，我不希望用户触发任何tr元素的点击，我应该写一个事件：

The reason I wanted a event which could only be fired through a script was, I didn't want users to fire the click of any of "tr" element, for which I should had written an event:

"click .reactive-table tbody tr": function clickTr() {...}

我没有具体回答这个问题，但我用这种方法解决了我的问题。

This is does not specifically answer the question,I had asked, but I solved my problem using this approach.
