我想基於當前選定的單選按鈕應用使用數據綁定的CSS樣式。基於在Knockoutjs中選擇的單選按鈕應用CSS樣式類綁定
下面是我嘗試應用的代碼,但不工作..
<input type="radio" value="mtn" data-bind="checked: setRadioVal, css: {lblstylebold: checkRadioEnabled(this)}" id="mtnradio">
<input type="radio" value="atn" data-bind="checked: setRadioVal, css: {lblstylebold: checkRadioEnabled(this)}" id="atnradio">
var ViewModel = {
setRadioVal: ko.observable(null),
checkRadioEnabled: function(value) {
if (value == ViewModel.setRadioVal())
return true;
else
return false;
}
}
ViewModel.setRadioVal("mtn") // This gets sets initially with either mtn or atn based on ajax response which I have not posted here. Just for understanding I have set as mtn.
因此,一旦用戶選擇了單選按鈕之一,setRadioVal
獲取與MTN無論ATN或更新。我試圖調用函數checkRadioEnabled
,並且當所選的當前單選按鈕值等於啓用值時返回true。但css類沒有得到應用。
當我調試時,我看到它在功能checkRadioEnabled
裏面單擊單選按鈕時,但值參數作爲窗口對象來。如何傳遞單選按鈕值並在函數內部訪問它checkRadioEnabled
? 我在這裏做錯了什麼?
