How to get length of MRVS row count from client script

[reddy8055]

Hi,

How can I get length of MRVS row count. I am tried using the below script to get length, I am able to get length in CMS view (alerts are showing correctly).But in Portal, I do not see any alerts if I use JSON.parse, I am able to see alerts incorrectly if i use stringify. Any help??

var mrvs = g_form.getValue('vta_training_details'); // internal name of your MRVS
//alert(mrvs);
var obj = JSON.parse(mrvs);
alert(obj);
var MRVSlength = obj.length;
alert(MRVSlength);

thanks,

Hi,

I also have similar usecase but JSON.parse is throwing error in console. My usecase is that I want to get the count of inserted rows in mrvs and that value I need to add in a client script of mrvs for some comparisons.

Can someone please help me on this.

JSON.parse() will throw an error if the thing you're passing into it isn't a valid JSON string, which suggests that either you're not getting the data from your MRVS correctly (ie: make sure you're using the correct internal name when calling `.getValue()`) or your MRVS is empty and has no rows (and you're not handling this scenario). It'd be best if you shared some code and the error.
