JQuery Knob显示数字变化

2022-01-11 00:00:00 jquery jquery-plugins php javascript

我正在使用 JQuery Knob 来制作一些很酷的图表，而且效果很好.但是我有一个问题:我想让图表之间的显示数字连接一个'％'符号.但我似乎无法让它发挥作用.通过 jquery 修改输入不会这样做，我已经尝试读入库的代码但没有运气.有没有其他人遇到过这个问题?

I'm using JQuery Knob to make some cool graphs and it's working perfectly. But I have one problem: I want to make the display number between the graph have a '%' symbol concatenated. but I just cant seem to make it work. Modifying the input through jquery wont do it, and I've tried reading into the code of the library but with no luck. Has any one else had this problem before?

推荐答案

如果您快速浏览一下 github 存储库，您会发现每次绘制画布时都会调用一个绘制钩子.如果你实现了那个钩子，你应该能够在输入中添加任何你想要的东西.这是您正在寻找的功能的简短示例(尝试一下:http://jsfiddle.net/eAQA2/)和供将来参考:

If you take a quick look at the github repo you'll see that there's a draw hook that's called everytime the canvas is drawn. If you implement that hook you should be able to add whatever you wish to the input. Here's a short example of the functionality you're looking for (to try it: http://jsfiddle.net/eAQA2/ ) and for future reference:

$(function() {
    $(".dial").knob({
      'draw' : function () { 
        $(this.i).val(this.cv + '%')
      }
    })
})

<input type="text" class="dial" data-min="0" data-max="100">
