it consists of 2 drop downs, first choice province in second drop down shows cities province. user choose city click go button when they've made choice, go link of choosing.

code below well.

html:

<select id="one"></select> <select id="two"><option><- select province</option></select><br /> <button id="button">go</button><br /> <div id="log"></div> 

jquery:

for (i=0;i<data.length;i++) {    $("#one").append(        $("<option>")        .attr("value",i)        .text(data[i][0])    ); } $("#one").on("change",function(){    var val = $("#one").val();     var prov = data[val][1];     $("#two").empty();     (i=0;i<prov.length;i++){        $("#two").append(         $("<option>").attr("value",prov[i]).text(prov[i])        );     } }); $("#two").on("change",function(){    var val = $("#two").val();     $("#button").off("click").on("click",function(){        //window.location = val; //customize url here.          //temporary demonstrate:         $("#log").text(val);     }); });
