Hi guys, here is a class I have and want it to be chain-able. Look at the
code sample first:
var myClass = new Class({
_isRunning : false,
Implements : [Options, Chain],
options: {
link : 'chain'
},
initialize : function(el, options) {
this.setOptions(options);
},
start : function(opts) {
if ( !this._checkChain() )
return this;
this._isRunning = true;
if ( !someConditions ) {
alert(this.$chain.length);
return this;
}
/* Where the actual process begins... */
},
_checkChain : function() {
if ( !this._isRunning )
return true;
switch ( this.options.link ) {
case 'cancel' : this.cancel();
return true;
case 'chain' : this.chain(this.caller.pass(arguments, this));
alert('link: '+this.options.link);
return false;
}
return false;
}
});
Now, the issue is, when 'someCondition' part doesn't break the actual
process, the chain can be stored just fine, and the flag _isRunning turns
to TRUE. However, when conditions doesn't match and the process returns
THIS, the chain seems to be ignored.
The actual process includes chain check and callChain methods, but note the
condition part, the length of chained functions is always 0 when the
function breaks.
Why is this happening?
