IE8淘汰赛错误 - 无法处理绑定 [英] IE8 knockout error - Unable to process binding

问题描述

我有这样的viewmodel，

I have a viewmodel like this,

var sectorViewModel = function() {
    this.currentValue = ko.observable();
    this.previousValue = ko.observable();
    ....
    this.maxValue = ko.computed(function() {
        return Math.max(this.currentValue(), this.previousValue(), ...);
    }, this);
}

ko.applyBinding(sectorVM, document.getElementById("divSector");

这是我正在进行数据绑定的html片段，

And this is the html snippet where I am doing the data-bind,

<div id="divSector">
    ...
    <div class="bar" data-bind="style: {width: (currentValue()*100)/maxValue() + '%'}"></div>
    ...
</div>

在IE8以外的所有浏览器中都能正常工作。在IE8中，我在开发工具中看到此错误 -

Works fine in all browsers except for IE8. In IE8 I see this error in dev tool -

无效参数。无法处理绑定style：function（）{return ...

任何想法如何让它在IE8中运行？

Any idea how can I get this to work in IE8?

谢谢。

推荐答案

调查从计算结果返回的确切结果。

Investigate the exact result that gets returned from your computed.

根据以下内容：

https://github.com/knockout/knockout/issues / 525

较新的浏览器可能会处理xx.asmanydecimalplacesrequired％等结果，但可能与IE8不兼容。您应该确保返回的值是IE8的兼容宽度样式属性 - 例如把它修剪到2位小数 - 这是我要尝试的第一件事。

The newer browsers probably handle a result such as xx.asmanydecimalplacesrequired% but may not be compatible with IE8. You should make sure the returned value is a compatible width style property for IE8 - e.g. trim it to 2 decimal places - that's the first thing I would try.

让我知道这是否有帮助，因为我通过研究完全搞清楚这一点，并且不要如果是这样的话，别忘记投票; P

Let me know if this helps, because I'm totally figuring this out via research, and don't forget to vote up if that's the case ;P
