如何使用淘汰赛禁用点击事件? [英] How to disable click event using Knockout?

问题描述

我有两个按钮，叫做

<a href='#' data-bind='click: clickActivateSpatialSearch' id='draw_polygon'>
<a href='#' data-bind='click: clickActivateSpatialSearchBox' id='draw_box'>

这里最好的是什么?我可以在$(document).ready上使用jQuery吗?问题是数据绑定单击在被按下时会禁用另一个单击事件，并且同样如此.但是当我按下相同的按钮时，它将再次启用第二个按钮.

What will be the best here? Can I use jQuery on $(document).ready? The problem is data-bind click disables the other click event when being pressed and likewise. But when I press same button, it enables the second button back once again.

所以我要说的是所有的胡言乱语，我只希望一次启用一个按钮.这可能与淘汰赛同时进行吗?如果是这样，请告诉我如何. PS:我已经在淘汰赛网站上查看了关于启用的信息，但是我不明白.我应该如何使其充分发挥作用?

So what I'm trying to say with all jibberish is that, I only want one button enabled at a time. Is this possible to coop together with knockout? And if so please tell me how. PS: I have looked on the knockout site about enable, but I do not get it. How I should get it to work fully?

推荐答案

您可以添加一个观察对象，其中包含按下了哪个按钮，然后将单击更改为检查该观察对象的函数:

You could add an observable that held which button was pressed then change the click to be a function that checked the observable:

<a href='#' data-bind='click: function() { 
    if(buttonClickedObservable() == 'polygon')
    {
        clickActivateSpatialSearch();
    }' id='draw_polygon'>
<a href='#' data-bind='click: function() { 
    if(buttonClickedObservable() == 'box')
    {
        clickActivateSpatialSearchBox'();
    }' id='draw_box'>

您将不得不决定如何设置可观察的物体.

You would have to decide how you set the observable though.
