[TYPO3-dev] ExtJS date pickers and date ranges (working prototype maybe for Core?)

[Stefano Cecere]

hi

i have quite finished my patch for this feature, BUT i would need some  
help with RegExp (i'm not good with it!)

to simply everything i pass the lower and upper date limits in the input  
classes, like

class="tceforms-textfield tceforms-datefield lower-100000 upper-2000000"

i can easily check the presence of those params within JS (with  .. . if  
(element.dom.className.match(/upper/)) {

QUESTION: qhat is the easiest way to get the parameter (100000 for  
example?)
i'd like to extract the "lower-100000" token, and then split by '-'

any help?

thank you!
