Hi, I am developing the full calender of jquery from some blog. I added my questions with concern this, but this question bit different. Full description of code is given here But not get satisfactory answers, so need to change the strategy . in this (in link given) code , action of controller returns the Json output and j query accepts it as same. but here I am confuse about J son. it errors me to add some json result allow like stupid parameter , which i passed , but while rendering it asking me to download that and after download finished , nothing happening there. So that I want to know can i do same thing by another way ? or any solution over this ? how to avoid download json and should proceed in functioning ?
