I am working on a project to upload multiple local csv files to csv layer via javascript api. Files are uploaded but only the first one is displayed. Can anybody help in this regard.

HI there, 

Please take a look at this simple test app. I am adding two csvlayers to the view in this app.

Hope this helps,

thanks Undral for your response. My scenarion is a bit different, i.e i am uploading multiple csv files and click on a upload button with file uploading code and pass it to a method like

public attachFiles(files){

let urlArray=[ ]

for (let i=0; i<files.length; i++){

files.item(i)

urlArray.push(URL.createObjectURL(files));              // pushing files like example.csv

}

urlArray.forEach(rec=>{

if(rec){

this.csvLayer.url=rec;

this.csvLayer.qeryFeatures().then(function(response){

addGraphipcs(response)   // drawing graphics for features

}

}

})

}

it works for one csv file, but i need to upload multiple files locally, anybody have idea how to do that.

I am not clear what you are trying to achieve. You are replacing the url of your csvlayer and the last url will win. You should be create a new csvlayer. 

this.csvLayer.url=rec;

Hi Undral,

I have an upload button for uploading multiple local  files on local drive(no http url) with lat long, and i am trying to plot all csv files via csv layer. How to do that, what's the best , either i have to merge multiple csv files into one csv file and then plot it or all can be combined and draw at a time by single csv layer. Your response will be appreciated.
