How to compare current date with ModifiedDate in SPlist

Question

I am looking for a solution :

Only for if condition to read first row's modified date and compare it current date [ ex today =21/01/2016 ]

condition :

if [ first row's Modified date == current date (Today)]

{

I have to do nothing

}

else

{

I will run my existing javascript to update all items

}

 

 

 Javascript :

var clientContext = null;
var globalCount = 0;
var itemCountList = 0;
var curentDate = new Date();

function uploadDest(){
clientContext = new SP.ClientContext("");
oList = clientContext.get_web().get_lists().getByTitle("");

camlQuery1 = new SP.CamlQuery();
query1 ='<View></View>';
camlQuery1.set_viewXml(query1);

this.collListItems1 = oList.getItems(camlQuery1);

clientContext.load(collListItems1);

clientContext.executeQueryAsync(Function.createDelegate(this, this.onMultiSelectListDataLoadQuerySucceeded1), Function.createDelegate(this, this.onMultiSelectListDataLoadQueryFailed));

}

function onMultiSelectListDataLoadQuerySucceeded1(sender, args){

listItemEnumerator1 = collListItems1.getEnumerator();
itemCountList = collListItems1.get_count();
while (listItemEnumerator1.moveNext()) {
oListItem1 = listItemEnumerator1.get_current();
oListItem1.update();
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));

}

}

function onMultiSelectListDataLoadQueryFailed(){
alert("error occured");
}

function onQuerySucceeded() {
globalCount = globalCount + 1;
console.log("success / "+ globalCount + "/" + itemCountList);
if(globalCount==itemCountList){
localStorage.setItem("code","1");
window.location = document.location.href;
location.reload();
}

}

function onQueryFailed(sender, args) {
console.log("error");
}

if(localStorage.getItem("code") === null){

ExecuteOrDelayUntilScriptLoaded(function(){
var div = document.getElementById("WebPartWPQ2");
div.style.opacity = 0;
uploadDest();

},"sp.js");

}else{
localStorage.removeItem("code");
}

}

</script>

Hello Payal , Refer below code

 

 

<script type="text/javascript" language="javascript"> 

function isGreater(date)

{ 

   if(this.getTime() > date.getTime())

   { 

      return true;

    } 

   else

   {    return false;

    }

 } 

Date.prototype.IsGreater = isGreater; //dd/MM/yyyy 

// Clearly instantiate a Date object with params as per your textboxes 

var dateOne = new Date();  

 dateOne.setFullYear(2001,12,31); // 31st December 2001 

var dateTwo = new Date(); 

 dateTwo.setFullYear(2002,1,1); // 1st Jan 2002     

 alert("Date Two is greater : " + dateTwo.IsGreater(dateOne));

 alert("Date One is greater : " + dateOne.IsGreater(dateTwo)); //I would use a custom validator with a function based on the above. 

</script>

Answer 5

Thank you so much for the fast resolution.

Actually , what I am looking for is : to compare current date=Today with aSharepoint list 's first item's Modified date.

 

So, I am not able to read that Sharepoint list's first item 's Modified date. 

So I want to add that if condition :

Current date == Modified date of 1st item in sharepoint list

then if condition fails

{

 

update list with :

 

listItemEnumerator1 = collListItems1.getEnumerator();
itemCountList = collListItems1.get_count();
while (listItemEnumerator1.moveNext()) {
oListItem1 = listItemEnumerator1.get_current();
oListItem1.update();
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}
