JSON.parse fails on space inside array

Question

I have saved this string in javascript

js_str= '{"id":"1","user_id":"1","cat_id":"1","name_bz":"Chitwan National Park","name_cf":"Gokarna","cf_lattitude":"27.525","cf_longitude":"87.56","boundry":"[[27.0656,85.255],[27.3564, 85.3564],[27.98998, 85.6898]]\n","area":"989.948","forest_conditon":"Poor","natural_regeneration":"High","grazing_pressure":"Medium","forest_type":"Natural","wild_species_list":"Tiger, Leopard, Rhino","others":null}';

On using js_arr=JSON.parse(js_str) it gives

SyntaxError: JSON.parse: bad control character in string literal at line 1 column 207 of the JSON data

column 207 is the space after comma [27.3564, 85.3564]. The whitespace in this place is giving error. i cannot use regex to remove whitespace as it would replace all whitespaces.

Column 207 is the space. What could be the control character. — neogeomat, Jan 24 '16 at 11:25
How are you getting the JSON string from server? Add that code also. — Tushar, Jan 24 '16 at 11:30

There is a \n in the wrong place or should be escaped. Try to change from:

"boundry":"[[27.0656,85.255],[27.3564, 85.3564],[27.98998, 85.6898]]\n"

to:

"boundry":"[[27.0656,85.255],[27.3564, 85.3564],[27.98998, 85.6898]]"

or escape it to:

"boundry":"[[27.0656,85.255],[27.3564, 85.3564],[27.98998, 85.6898]]\\n"

That is not the problem. That character there is valid JSON. – Bart Friederichs Jan 24 '16 at 11:28

I think the \n should be removed or escaped – Wagner Tsuchiya Jan 24 '16 at 11:30

the new line char needs to be escaped http://stackoverflow.com/questions/42068/how-do-i-handle-newlines-in-json – Wagner Tsuchiya Jan 24 '16 at 11:40

Just add a \ before \n control character and all will be fine. JSON parser works like this.

js_str= '{"id":"1","user_id":"1","cat_id":"1","name_bz":"Chitwan National Park","name_cf":"Gokarna","cf_lattitude":"27.525","cf_longitude":"87.56","boundry":"[[27.0656,85.255],[27.3564, 85.3564],[27.98998, 85.6898]]\\n","area":"989.948","forest_conditon":"Poor","natural_regeneration":"High","grazing_pressure":"Medium","forest_type":"Natural","wild_species_list":"Tiger, Leopard, Rhino","others":null}';

JSON.parse(js_str)

Successfully tested code in Mozilla Firefox.

the \n is coming as a string from database . I cannot change it. Is there another way. — neogeomat, Jan 24 '16 at 14:28
