Question

I am new to JavaScript, I have a very basic question.

I have this each statement within an alert in my each statement which is working perfectly:

alert( " <g:each in="${index}"> ${""+it.indexDate+""+it.value }  </g:each>  " );

Now I have this variable:

var todaysDate = new Date ;

I want to check if the above indexDate is same as todaysDate.

How can i exactly do this?

Thanks.

If you want to compare to the precision of miliseconds, you compare the getTime() value of both Date Object.

if (it.indexDate.getTime() === todaysDate.getTime() ) {
  //Do something when todaysDate is it.indexDate
}

If you want to compare only the Date part, you compare the getDate() value.

if (it.indexDate.getDate() === todaysDate.getDate() ) {
  //Do something when todaysDate is it.indexDate
}

In Grails framework, you use the following code

<g:each in=${index}>
  <g:set var="todaysDate" value="${new Date()}" />
  <g:if test="${it.indexDate.getTime() === todaysDate.getTime()}">
      //code when the comparison passes
  </if>
</g:each>
