關於為空必填js判斷

為了減少一不必要的if邏輯判斷，自已寫了一個方法

$(function () {
    $("#btnAdd").click(function () {
        var strLinValu = ".combo-text" + "," +"#txtCpname"+ "," + "#txtCPS" + "," + "#txtPhone" + "," +"#txtFax" + "," + "#txtAddress1"
        if (chkInputVal(strLinValu))
            return false;
        else
            return true;
    });
})

function chkInputVal(strlin) {
    var strArry = strlin.split(',');
    var Flag = false;
    for (var i = 0; i < strArry.length; i++) {
        if ($(strArry[i]).val() == "" || $(strArry[i]).val() == null) {
            $(strArry[i]).focus(); //對應的元素ID獲取焦點
            Flag = true;
            break;
        }
    }

    return Flag;
    
}
