jQuery UI Slider - Value returned from 'slide' event on release is different from 'change' value
提问by wyqydsyq
I have a jQuery UI slider:
我有一个 jQuery UI 滑块：
$('div.slider').slider({
range: true,
step: 250,
min: 1000,
max: 500000,
values: [1000,500000],
change: function(event, ui){
console.log($(this).slider('values', 0)+','+$(this).slider('values', 1));
},
slide: function(event, ui){
console.log($(this).slider('values', 0)+','+$(this).slider('values', 1));
}
});
For some odd reason, when releasing the slider (mouseup) the value changes slightly from what it was. The slide event is returning something different than what the change event is. Anyone have any ideas what might be causing this and how I could solve it?
出于某种奇怪的原因，当释放滑块（鼠标向上）时，该值与原来的值略有不同。幻灯片事件返回的内容与更改事件不同。任何人都知道可能导致这种情况的原因以及我如何解决它？
I'm going to have a pretty intense operation in the callback for the change event (meaning I can't just use sldie), but also need to show the values of the slider live, so I can't use just one or the other.
我将在 change 事件的回调中进行非常密集的操作（意味着我不能只使用 sldie），但还需要实时显示滑块的值，所以我不能只使用一个或其他。
Here's a fiddle with this oddity in action: http://jsfiddle.net/5W6Zh/

Thanks in advance
提前致谢

we ran into this tonight (and last night, and for the past few months). What we did to fix it was use ui.value and ui.values[0] instead of $("#slider").slider('values',0).
我们今晚（以及昨晚和过去几个月）遇到了这个问题。我们为修复它所做的是使用 ui.value 和 ui.values[0] 而不是 $("#slider").slider('values',0)。
Use this:
用这个：
change: function(event, ui) {
$('.values').text(ui.values[0] + ',' + ui.values[1]);
}
Instead of:
代替：
change: function(event, ui) {
$('.values').text($(this).slider('values', 0) + ',' + $(this).slider('values', 1));
}
I forked your jsfiddle and made it work: http://jsfiddle.net/danhixon/9JdhU/1/
我分叉了你的 jsfiddle 并使它工作：http: //jsfiddle.net/danhixon/9JdhU/1/
Honestly I don't think I would have found the solution without your question and jsfiddle - I kept comparing it to the jquery-ui demo until I found this difference.
老实说，如果没有您的问题和 jsfiddle，我认为我不会找到解决方案 - 我一直将它与 jquery-ui 演示进行比较，直到我发现这种差异。

I found a solution! ALWAYS do this on a slide event:
我找到了解决办法！始终在幻灯片事件上执行此操作：
$(this).slider('value', ui.value);
And you're good to go
你可以走了

Use ui.value in the slide handler to get a more accurate value.
在幻灯片处理程序中使用 ui.value 以获得更准确的值。

Your min, max and step values look a bit weird, but I guess you just got them mixed up.
你的最小值、最大值和步长值看起来有点奇怪，但我猜你只是把它们搞混了。
I found that the slider doesn't work too well with steps much smaller than 1, so I changed to use integers only and divide afterwards. Never had any problems since then.
我发现滑块在步长远小于 1 时效果不佳，因此我改为仅使用整数，然后再进行除法。从那以后再也没有任何问题。
