JSON parsing and DataGrid column repeat Problem __js

Just internship contact project, in the accumulation of experience, welcome to Exchange

Some time ago encountered JSON parsing and DataGrid column duplication problem, deliberately recorded, easy to view later.

JS Code:

function Search () {$ (' #gridList '). DataGrid ({Url:sy.contextPath + '/integratedsearchenterprise/findjointrade '), Method: ' Post ', Queryparams: $ ("#searchForm"). Serializejson (), Pagination:true, Striped:t
        Rue, Nowrap:false, Singleselect:false, Fit:true, Collapsible:true, Loading:true, Loadmsg:loadmsgs, Fitcolumns:true, Showheader:true, Pagenumber:1, pagesize:pagesizes , Pagelist:pagelists, Rownumbers:true, IDfield: ' id ', sortname: ' id ', Sortord ER: ' desc ', columns:[[{field: ' Basenumber ', title: ' Enterprise Number ', align: ' Left ', sortable: ' True ', Width: ' 5% '}, {F Ield: ' Cnname ', title: ' Industry name ', align: ' Left ', sortable: ' True ', Width: ' 22% '}, {field: ' Enterprisetrade ', title: ' Business Scope ',
	      	Align: ' left ', sortable: ' True ', Width: ' 5% ', formatter:function (value) {return value[0].scopename; }, {field: ' Opendate ', title: ' Opening date', align: ' Left ', sortable: ' True ', Width: ' 10% '}, {field: ' Businessstatus ', title: ' Operating state ', align: ' Left ', sortable: ' true ', 
                Width: ' 10% ', Formatter:function (val) {return businessstatusmap[val]; }, {field: ' Manageclass ', title: ' Karma Category ', align: ' Left ', sortable: ' True ', Width: ' 10% ', formatter:funct
                Ion (Val) {return enterprisetypemap[val]; }, {field: ' Enterprisetrade1 ', title: ' Managed Enterprise ', align: ' Left ', sortable: ' True ', Width: ' 23% ', formatter	
             : function (value,rowdata,rowindex) {return rowdata.enterprisetrade[0].trusteeid; }, {field: ' Enterprisetrade2 ', title: ' Governing Body ', align: ' Left ', sortable: ' True ', Width: ' 7% ', formatter:function (valu	
             E,rowdata,rowindex) {return enterprisemanagerence[rowdata.enterprisetrade[0].manageragence]; }, {field: ' id ', title: ' Operations ', align: ' left ', Width: ' 8% ', formatter:function (value, row, Index) {var v = ';
                    V + + viewbtn (row.id);
            return v;
        	}], Onloaderror:function () {$.messager.alert (Warningtitle, errormsgs, ' warning ');
        Closeprogress ();
		},onbeforeload:function (param) {startprogress ();
			}, Onloadsuccess:function (data) {Cleargrid (' #gridList '));
		Closeprogress (); 
}
    }); }

All the focus is to look at the format of JSON, curly braces, brackets, and the juxtaposition between them, all need to be clear before you can make a specific resolution.

and the column repeats in the DataGrid, a random column name is written, and then the corresponding method is invoked.
