View Full Version : How to know about a object's methods/properties ?

24 Jul 2012, 5:40 AM
I need to set the tip height in the chart dynamically. So, is there any function do this ?

I used console.log(<object-name>) But I can find only the properties for that and not the methods. Please Help on this !

I was able to identify my tip height by chart_id.series.items[0].tips.height

But how to set the tip height ?

http://docs.sencha.com/ext-js/4-0/#!/api/Ext.tip.Tip (http://docs.sencha.com/ext-js/4-0/#!/api/Ext.tip.Tip)

if you do a console.log(tipObject).. you should be able to find the methods in __proto__

Another fairly easy way to do this is via the renderer in the tips config:

tips: {
height: 30,
width: 70,
trackMouse: true,
renderer: function(storeItem, item) {
var fieldValue = storeItem.get('someField');

// if text length greater than 50 characters, increase tip height.
if (fieldValue.length > 50) {
this.height = 100;
