jquery - How to know whether solr server is running or not -


i've got problem can't solve. partly because can't explain right terms. i'm new sorry clumsy question.

below can see overview of goal.

i'm using magento ce 1.7.0.2 & solr 4.6.0.

var url1 ="http://127.0.0.1:8080/solr/select?q=iphon&wt=json&json.wrf=?"; $.getjson(url1,function(result){    // logic  });

when solr server running means script working fine.but if solr server not running means it'll not work.

but goal write script this...

if( solr server running){    var url1 ="http://127.0.0.1:8080/solr/select?q=iphon&wt=json&json.wrf=?";    $.getjson(url1,function(result){       // logic-1    }); }else{    // logic-2 }

so how know whether solr server running or not ?

& know duplicate question never find solution please ignore it.

any ideas ?

don't know how solr works, proper jquery be:

$.ajax({     type: "get",     url: "http://127.0.0.1:8080/solr/select?q=iphon&wt=json&json.wrf=?",     datatype: "json",     success: function (result) {         // working     },     error: function (result) {         // not     } });
