I encountered a problem with JSON parsing that resulted in a SyntaxError: "JSON.parse: bad escaped character" while handling an AJAX success event. The AJAX code in question is as follows:
$("#ajaxform").submit(function(e) {
$.ajax({
url : '/cart/add',
type : 'POST',
contentType : 'application/x-www-form-urlencoded',
data : $(this).serializeArray(),
dataType: 'json',
success : function(content) {
$("#result").append(content.addToCartLayer);
$.fancybox({
href : '#result',
showCloseButton : false,
enableEscapeButton : false,
hideOnOverlayClick:false
});
},
error : function(xht, status, ex) {
console.log("error : " + ex);//JSON.parse: bad escaped character
}
});
}
The corresponding Java code snippet is as follows:
@RequestMapping(value = "/cart/add", method = RequestMethod.POST, produces = "application/json")
public String addToCart(@RequestParam("productCodePost") final String code, final Model model,
@Valid final AusAddToCartForm form, final BindingResult bindingErrors, final RedirectAttributes redirectModel)
{
// MY LOGIC HERE
return ControllerConstants.Views.Fragments.Cart.AddToCartPopup;
}
The issue arose when attempting to modify the color value of a product in the cart from "RED" to "R'NB," resulting in the AJAX exception being thrown (JSON.parse: bad escaped character).
I have attempted to resolve the problem by adding @ResponseBody to my method, but to no avail.
So, my question is, how can I address this issue? Any additional details or clarification needed, please let me know.
