Jquery ajax transmits an array in the background action

Jquery ajax transmits arrays to the background. The idea at the beginning was: directly var array = new Array (), and then assign this array to a parameter that needs to be passed to the backend when Ajax is used for submission. It seems that everything goes well. This is not the case. If you have any questions about the principle of http://www.iteye.com/problems/56240? All arrays transmitted to the background must be converted to strings. For example, if two name Information Names = aaaa name = bbb is a GET request, it can be converted to: http: // localhost/xxx? Name = aaa & name = bbb; for a POST request, the parameter cannot be directly written as param: {name = 'aaa', name = 'bbb '}. If you use this parameter, only the value of name = bbb will be obtained in the background. What should I do? My solution is to use List or array reception in the background. The foreground needs to use a js script to separate multiple identical parameters such as name, and assemble parameters through the "," separator to form a ", to the background. Example: jquery ajax and spring3 mvc: 1. html element <input name = "item" type = "checkbox" value = "2001"/> payment <input name = "item" type = "checkbox" value = "2002 "/> query <input name = "item" type = "checkbox" value = "2003"/> reconciliation <input name = "item" type = "checkbox" value = "2004 "/> withdrawal 2. jquery code var info = ""; var items = $ ('[name = "item"]: checkbox: checked'); for (var I = 0; I <items. length; I ++) {// If I + 1 is equal to the length of the option, add an empty character Otherwise, it is a comma (info + items. get (I). value) + (I + 1) = items. length )? '': ',');} $. Ajax ({type: 'post', url: "addPartnerInfo.html", dataType: 'text', data: {interface: info}, success: function (data) {alert (data) ;}}); java code @ RequestMapping (value = "/addPartnerInfo", method = RequestMethod. POST) public @ ResponseBody String addPartnerInfo (String [] interface) {System. out. println (interface); return "OK ";}
