如何使用getValue（）获取日期

Question

HTML:

<div class="input-group">
    <div class="input-group-prepend">
        <span class="input-group-text">From</span>
    </div>
    @(Html.DevExpress().BootstrapDateEdit("dtReturnDateFrom").EditFormat(EditFormat.Custom).DisplayFormatString("dd MMM yyyy").EditFormatString("dd MMM yyyy").UseMaskBehavior(true).AllowNull(false).Value(@DateTime.Today - TimeSpan.FromDays(365)))
</div>

jQuery

$(document).ready(function () {
    $M.Report.onLoadReport = function (varReportNm, varTemplateNm) {    
    dtTempReturnFrom = $('#dtReturnDateFrom').getValue();
    dtTempReturnTo = $('#dtReturnDateTo').getValue();
    tempReturnFrom = dtTempReturnFrom.getFullYear() + "-" + dtTempReturnFrom.getMonth() + "-" + dtTempReturnFrom.getDay();
    return {        
        /////////// addd this
        format: varTemplateNm,  
        dtReturnDateFrom: tempReturnFrom,   
    };
}
});

The error that I get.

I have try find the solution at google but most the solution was not work with my code.

GetValue is not a function

Answer 1

$('#dtReturnDateFrom') will be a jquery object & in jequery there is no getValue() function .Use val() insetad of getValue();

If you wish to create a custom function getValue you need to extend jquery and create a function getValue and define it's body

 jQuery.fn.extend({ getValue: function() { return $(this).val(); } }); let k = $('#someId').getValue(); console.log(k) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type='text' id="someId" value="test Value ">
