I have a problem with my jQuery script that send data via POST method. The problem is whenever it sends data via Ajax that has an "&" ampersand in the sentence
You can use a native javascript escape() function
In line 74
data: : "&task_d=" + escape(task_d) + ""
Alternatively, you could enclose your query string values in quotes
data: : "&task_d='" + task_d + "'"
