Utility method for returning a default value if the passed value is empty.
- *The value is deemed to be empty if it is
-Ext.addBehaviors({
- // add a listener for click on all anchors in element with id foo
- '#foo a@click' : function(e, t){
- // do something
- },
-
- // add the same listener to multiple selectors (separated by comma BEFORE the @)
- '#foo a, #bar span.some-class@mouseover' : function(){
- // do something
- }
-});
- * example:
-ImageComponent = Ext.extend(Ext.BoxComponent, {
- initComponent: function() {
- this.autoEl = { tag: 'img' };
- MyComponent.superclass.initComponent.apply(this, arguments);
- this.initialBox = Ext.copyTo({}, this.initialConfig, 'x,y,width,height');
- }
-});

-// Example 1:
-Ext.partition([true, false, true, true, false]); // [[true, true, true], [false, false]]
-
-// Example 2:
-Ext.partition(
- Ext.query("p"),
- function(val){
- return val.className == "class1"
- }
-);
-// true are those paragraph elements with a className of "class1",
-// false set are those that do not have that className.
- *
-// Example:
-Ext.invoke(Ext.query("p"), "getAttribute", "id");
-// [el1.getAttribute("id"), el2.getAttribute("id"), ..., elN.getAttribute("id")]
- *
-// Example:
-Ext.pluck(Ext.query("p"), "className"); // [el1.className, el2.className, ..., elN.className]
- * Zips N sets together.
- *
-// Example 1:
-Ext.zip([1,2,3],[4,5,6]); // [[1,4],[2,5],[3,6]]
-// Example 2:
-Ext.zip(
- [ "+", "-", "+"],
- [ 12, 10, 22],
- [ 43, 15, 96],
- function(a, b, c){
- return "$" + a + "" + b + "." + c
- }
-); // ["$+12.43", "$-10.15", "$+22.96"]
