复选框中的剔除数据绑定不适用于Android（4.2）

Question

There is an issue with data binding in my html control using Knockout JS:

I have following input checkbox

<input type="checkbox" id="chbText" data-mini="true" data-bind="checked: chkAddLabel"  />

I have bind chkAddLabel property to show/hide some div using following code

 this.IsShowDiv = ko.computed(function () {
     return this.chkAddLabel();
 }

and finally the div

<div data-bind="visible: IsShowDiv"></div> 

This same code is working fine on Windows OS browsers (Chrome, IE, firefox) but not working on Nexus 7 and Nexus 5.

Answer 1

You need to copy the this variable to local variable. Suppose consider it as self . We need to do this because every function having default variable this because of the parent this is override with new this .

var self = this;
self.IsShowDiv = ko.computed(function () {
 return self.chkAddLabel();
}
