date string in json object retrieved by urlAdaptor is being converted to date object

After version 16.3.0.21 ej-grid with UrlAdaptor datamanager automatically converts date string to date object before databinding and rendering.

thus the converted object date "Fri May 11 2018 02:00:00 GMT+0200 (Central European Summer Time)"  will be showed in grid column instead of string "2018-05-11" !

I had analysed the scripts and found out which there is a method called jsonReviver in ej.data.js which contains a code line with date pattern testing regex,

which in version 16.3.0.21 and before it will not match a string date, but after that version it will match.

here is the code for ej.data.js version 16.3.0.21:

     else if (/^(\d{4}\-\d\d\-\d\d([tT][\d:\.]*){1})([zZ]|([+\-])(\d\d):?(\d\d))?$/.test(value))

and for next versions is:

     else if (/^(\d{4}\-\d\d\-\d\d)|(\d{4}\-\d\d\-\d\d([tT][\d:\.]*){1})([zZ]|([+\-])(\d\d):?(\d\d))?$/.test(value))

I need to show exactly the string date as it has retrieved from json, so please fix this,

or define an option in grid or datamanager which bypasses this behaviour.

Thanks

Thanks

it had worked completely.

but this is just a workaround, the data processing routine (in ej.data.js) should not change the data type retrieved from json, unless user asks so.

specially for string values.

the workaround you gave, is forcing me to alter 50 views in my project (or in other way alter 50 models).

I have a list containing date string values, which will be retrieved as json using UrlAdaptor.

all of data are converted to date objects and therefor a list of "undefined" will be returned!

Hi Mahyar, 

 

Query: “the data processing routine (in ej.data.js) should not change the data type retrieved from json” 

 

By default we will parse the date string to date Object before binding it to Grid or dropdownlist (i.e while serializing). But if you want to string to be as it is kindly disable the boolean (ej.dateParse) in your sample.  

 

 

Since you want to apply the changes in the multiple view pages. We suggest you to refer the below script file (dateparse.js) after the ej.web.all js file reference.  

 

Please get the script file from the below location.

Please remove the previous suggestion, when referring the above script file. 

 

Note: Using above solution will resolve the issue related to EJ1 Dropdownlist also.  

 

Please get back to us if you have further queries.

Thanks for your help

it worked great.

as i had put the ej.dateParse = false in the Layout file

i hope changing it does not effect somewhere else in the code (for example where the date should be parsed as object) ;-)

I also have a Grid which is loaded with local data (ej.isJSON) with some string columns containing string dates (like: 2019-03-07).

but the dates are being parsed and showed then.

changing ej.dateParse has no effect on this as it is local data.

the only way to make it working is to add "{0:yyyy-MM-dd}" Format option to the specified column in EJ().Grid, 

but here another problem comes up which is exporting to excel, which dates will be exported and showed as "2019-03-07T00:00:00.000Z

" which is not the result i want!

 

i'm not sure, maybe it's better to redefine "ej.parseJSON" method as it can be done without manipulating ej.data.js,

or you should consider placing ej.dateParse flag in p.parseJson method in future releases..
