Poll the DOM for a given node to see when it is ready for access. Callback is fired when the node is ready.

$ component install jamischarles/node-ready

var isNodeReady = require("node-ready");
//isNodeReady(query, success, failure, cfg); First 2 params are required.
isNodeReady('.btns', function(nodes){
  console.log('success!');
});
//example with all params passed in
var cfg = {
  timeout: 10, //timeout with failure after 10 seconds if query not found. Default is 5 seconds.
  interval: 300, //poll the DOM for the node query ever 300 ms. Default is 200 ms.
  debug: true //output console.logs()
}
isNodeReady('.btns', function(nodes){
  console.log('success!');
}, function(query){
  console.log('failure...');
}, cfg);

Params:

• query (String): Can be any jquery-like query. Zest is used for the selector engine.
• success (function): Pass in a callback function that's called when the node is found in the dom. Returns an array of nodes found matching the query.
• failure (function): (Optional) Pass in a callback function that's called when query doesn't find anything in the dom after the timeout period (default is 5 seconds). Returns a string of the query not found.
• cfg (object): (Optional) Pass in a configuration object to override the defaults. {timeout: 10, interval: 100, debug: true}
