问题描述
当我添加获取错误时
未捕获错误：无法解析绑定。
消息：ReferenceError：未定义AcSource;
绑定值：选项：$ root.acSource，optionsText：'Name'，optionsValue：'Value'，value：AcSource
我尝试了什么：
i已经在cshtml中写过，如下所示
when i am adding getting error like
Uncaught Error: Unable to parse bindings.
Message: ReferenceError: AcSource is not defined;
Bindings value: options: $root.acSource, optionsText: 'Name', optionsValue: 'Value', value: AcSource
What I have tried:
i have wrote in cshtml like below
<div class="textBoxStyling mandatory">
<h4>Ac Source</h4>
</div>
和淘汰赛中添加了
and in knockout have added
acSource: ko.observableArray([{ Name: "EB", Value: 1 }, { Name: "DG", Value: 2 }, { Name: "EB & DG", Value: 3 }])
推荐答案
root.acSource，optionsText：'Name'，optionsValue：'Value'，value：AcSource
我尝试了什么：
i用cshtml写的如下
root.acSource, optionsText: 'Name', optionsValue: 'Value', value: AcSource
What I have tried:
i have wrote in cshtml like below
<div class="textBoxStyling mandatory">
<h4>Ac Source</h4>
</div>
并且在淘汰赛中添加了
and in knockout have added
acSource: ko.observableArray([{ Name: "EB", Value: 1 }, { Name: "DG", Value: 2 }, { Name: "EB & DG", Value: 3 }])
尝试这个
try this
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head >
<title></title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.0/knockout-min.js" type="text/javascript"></script>
</head>
<body>
<select data-bind="options: acSource, value:AcSource, optionsText: 'Name' , optionsValue: 'Value' "></select>
<script>
function myModel() {
this.acSource = ko.observableArray([{ Name: "EB", Value: 1 }, { Name: "DG", Value: 2 }, { Name: "EB & DG", Value: 3 }]);
this.AcSource = ko.observable();
}
ko.applyBindings(new myModel());
</script>
</body>
</html>
