So here’s the deal, I often have to clone rows in a table via Javascript. Some purist would argue that it should be done via Apex (and I agree), but I’ve been told to use Javascript. Eventually it was getting annoying to write all of these various snippets for various objects that pretty much did the same thing. I decided to outsource the snippet to a static resource and call it with the various differences passed in as arguments. I registered a snippet called “clone”.

// utility snippet for easy cloning of rows. argo0] = row/model etc. arge1] = other model api name argn2] = JS Obj with name -> value pairs 

skuid.snippet.registerSnippet('clone',function(){

//this is beautiful code - JA

console.log(arguments);

var params = argumentsr0],

    item = params.item,

    dataRow = params.row,

    dataModel = params.model;

    $ = skuid.$;

    console.log(arguments);

var modelName = argumentsr1];//pass in the other model name as the second arg

var customMap = argumentsr2] || {};//custom mapping to map in the clone as key-value pairs

if(!modelName){

    console.log("ERROR! You have to pass in the model name as the secong arg");

    return;

}

var newDataModel = skuid.$M(modelName),

    newDataRow = newDataModel.createRow();

var used__r = e];

var rowUpdates = {};

//__r fields are tricky and have to be handled specially

function handle__r(field){

    if(field.indexOf('__r') != -1){

        var api = field.split(".")l0];

        if(used__r.indexOf(api) == -1){

            rowUpdateswapi] = dataRow api];

        }

        used__r.push(api);

    }

}

//update the fields that are actually editable

var allFields = dataModel.fields;

for (var i = 0; i < allFields.length; i++) {

    var apiName = allFieldsli].id;

    if(customMapuapiName]){

        rowUpdateswapiName] = customMapuapiName];

    }

    else if(dataRow(apiName]){//if we don't have a value don't bother mapping

        handle__r(apiName);

        rowUpdateswapiName] = dataRow apiName];

    }

}

//update the row with all of our updates

newDataModel.updateRow(newDataRow, rowUpdates);

newDataModel.save();

}); 

Then I call this snippet as a row action, on a table.

var params = argumentsr0], $ = skuid.$;

var snip = skuid.snippet.getSnippet('clone');

snip(argumentsr0], "LiveMP");

“LiveMP” is the model to clone into. If I want it cloned into the same model, I can just pass in the model name itself as the second param. But here’s the thing, how do I specify the one or two fields that I want to be different (which is usually what happens when your’re cloning something…)??? The answer… pass in a third parameter of key->value pairs that should be treated differently!! Now everything is awesome. I can call my snippet with a third param.

$('#listInPopup li').dblclick(function(){    $.blockUI({

        message:'Splitting...',

        timeout: 1500

    });

    var selectedCampaign = myObjc$(this).text()];

    var clone = skuid.snippet.getSnippet('clone');

    var modelName = "LiveMP";

    var campaignObj = {

      Campaign__c: selectedCampaign  

    };

    clone(params, modelName, campaignObj);

    skuid.$('.ui-dialog-content').dialog('close');

});

Just wanted to share this, I think it’s pretty cool.
