jquery - Copying a ColdFusion cfparam array into a JavaScript array -

i've have cf page who's inventory search form, frm_inv post's itself. frm_inv's main table of records, tbl_inv, uses tablesorter. hidden input (sort_list) used in conjunction cfparam keep track of tbl_inv's sortlist:

main.cfm

<cfparam name="form.sort_list" type="string" default="1,0">  <form id="frm_inv" action="main.cfm" method="post">     <input name="sort_list" type="hidden" value="#form.sort_list#"/>     <table id="tbl_inv" class="tablesorter">         ...     </table> </form> 

when frm_inv submitted, cf uses sort_list in $(document).ready() restore tbl_inv's sort order:

$(document).ready(function(){     var sort_list_str = <cfoutput>"#form.sort_list#"</cfoutput>;     var sort_list = sort_list_str.split(",");      $("#tbl_inv").tablesorter({         textextraction: ['complex'],                 sortlist:[[sort_list[0],sort_list[1]]]     }).bind("sortend", function(sorter) {                    var sl = sorter.target.config.sortlist;         $("input[name='sort_list']").val(sl.tostring());     }); }); 

i rather use arrays convert comma separated string array i'm doing

<cfparam name="form.sort_list" type="string" default="1,0"> <cfparam name="form.sort_list" type="array" default="arraynew(2)"> 

however need know proper javascript , coldfusion syntax in order pose that's relevant in arrays exclusively.

copying coldfusion ... array javascript array

why? part, http transmits strings, there no translation between client , server complex types. unless doing more passing sort value , forth, converting between client , server side arrays unnecessary complication. simpler leave value string , splitting or parsing on client side.

you did not explain problem trying solve, .. there nothing inherently wrong current approach. however, simplified bit. there no need cfoutput variable again here:

(a) var sort_list_str = <cfoutput>"#form.sort_list#"</cfoutput>;

since stored current form.sort_list value in hidden form field, above redundant. instead, read field's value javascript ie

(b) var sort_list_str = $("input[name='sort_list']").val();

having said that, if prefer work arrays, store json string representation of arrays instead. use parse() , stringify() convert arrays , forth. same net effect current method, bit simpler in terms of code.

form:

<cfparam name="form.sort_list" default="[[1,0]]"> ... <input id="sort_list" name="sort_list"       type="hidden" value="#encodeforhtml(form.sort_list)#" /> ... 

jquery:

$(document).ready(function(){     $("#tbl_inv").tablesorter({         textextraction: ['complex'],                 sortlist: json.parse($("#sort_list").val())     }).bind("sortend", function(sorter) {                    var sort_arr = sorter.target.config.sortlist;         $("#sort_list").val(json.stringify(sort_arr));     }); });
