How to update from json data?

[lharland]

Hi, I wanted to use the clusterize.update method but couldn't get it working. How does clusterize know how to format the html based on the objects in the Json data?

Hi Clusterize can't update specific rows, .update() method expects full list of rows.

For example you have initialized clusterize with

rows: ['<li>1</li>', '<li>2</li>', '<li>3</li>']

If you want to change second tag to be 5, you have to do

.update(['<li>1</li>', '<li>5</li>', '<li>3</li>'])

If you need to update list really often - better set verify_change: true while init clusterize.

It will save you from unnecessary DOM update in case when you are located in one cluster but updating row located in another cluster.

How can i give JSON Object as input in clusterize.js ?

[NeXTs]

@KalaiselvanMahendran you need to convert your JSON to array of strings. See https://github.com/NeXTs/Clusterize.js/issues/28#issuecomment-114988544

@NeXTs if i have millions of records how can i convert all the record as strings? it takes time to put a millions of data into the loop to convert it has a string. Is there any option like directly passing an array of JSON object?

I understand that

but clusterise does not process any data. It requires array of tags in strings, so there aren't other ways of providing data except ['1', '2']

You need to find a way to convert your json in non-blocking way, for example partially by "chunks" using setTimeout loop
