[Proto-Scripty] Prototype's selector as well as eq in Jquery

2012-09-23 Thread Евгений Шморгун 


I have to assign the different sizes to the td, and the width of them 
depends on the number's position of the tag in table.

In Jquery I can write

$$('td .yui-dt-liner 
div[id^=yui-gen]').eq(2).invoke(setStyle,{'width':'122px'});

changing the argument in eq. is there analogue expression in prototype.js ?

Thanks!

Sure. if you start at the tr that holds the tds, you can use down() to do this. 
If you want the second td to have a certain width, you could do this:

$$('tr').each(function(elm){
elm.down('td', 2).setStyle('width:122px');
});

You could probably also use

$$('td .yui-dt-liner div[id^=yui-gen]')[2].setStyle('width:122px');

for individual calls - but if you are going through multiple elements I
would use each as Walter described
