Currently I have a functioning code for dynamically adding and removing form inputs on my page. I have multiple forms that I need to include on the page, so I made an event action where they could press a button and it would hide all the forms except the relevant one. This worked fine, but it created a conflict with my jQuery/javascript code because the code uses a class name to dynamically add or remove input fields. Both forms would have to be under the same class name for me to use the jQuery function as is, but that creates conflict and the function stops working. I could just write two versions of the function (one for each class), but I'm trying to find a way to generalize this, so that I don't have to have so many functions. I was thinking about doing something like this:
$('.ccinput').addClass('dinput').removeClass('ccinput');
where I would change each form's class name accordingly, so that they would be the only ones communicating with the jQuery function. This method seems to be very error prone, especially with more than 2 forms (I plan on having 4 forms total). Do you guys know of another way that I can accomplish this? Here is my html code for reference:
EDIT: I've made significant changes to the code, so here is the new version. I removed all the ID values from the form inputs and changed the jQuery function so that it does not use ID values as selectors. This removed some conflicts. And I'm now trying to use attr('class','newclass') so that the jQuery function works for both codes. It seems to work perfectly for the first form, but it refuses to function for the second. I have no idea why.
