javascript - Preventing a async load function from being called repetitively in a click event -

i have callback function loads page of info @ time. function gets called/triggered when , next links clicked. run issues animation , load completing in time when end user fast, subsequent clicks of next link , repetitively calls load function. realize async call, there way queue or pause loads/animations 1 load not running before other 1 finished?

function nextpagenav_click() { var curpage = parseint($('#curpage').attr('value').tostring()) + 1; $('#curpage').attr('value', curpage); loadpage(curpage, 'next'); } function loadpage(curpage, state) { $.ajax({ type: "post", url: "defaulttmp3.aspx/getlatestprofiles", cache: true, async: false, data: "{'pageindex': " + curpage + "}", contenttype: "application/json; charset=utf-8", datatype: "json", success: function (msg) { switch (state) { case 'previous': $('<div id="nextitems"></div>').insertbefore('#curitems'); $('#nextitems').empty(); $('#nextitems').settemplateurl('page/public/templates/profiletemplate.htm'); $('#nextitems').processtemplate(msg); $('#items').attr('style', 'left:-920px'); $('#items').animate({ "left": "+=920px" }, 500, function () { $('#curitems').remove(); $('#nextitems').attr('id', 'curitems'); } ); break; case 'next': $('<div id="nextitems"></div>').insertafter('#curitems'); $('#nextitems').empty(); $('#nextitems').settemplateurl('page/public/templates/profiletemplate.htm'); $('#nextitems').processtemplate(msg); $('#items').animate({ "left": "-=920px" }, 500, function () { $('#curitems').remove(); $('#nextitems').attr('id', 'curitems'); $('#items').attr('style', 'left:0'); } ); break; default: $('#curitems').empty(); $('#curitems').settemplateurl('page/public/templates/profiletemplate.htm'); $('#curitems').processtemplate(msg); break; } var rowsreturned = parseint(msg.d.rowsreturned.tostring()); var pagesize = parseint(msg.d.pagesize.tostring()); initprevnextlinks(rowsreturned, pagesize, curpage); }, error: function (request, status, error) { alert(request.statustext); } }); }

rather, seek throttling click

var throttleasync(callback, time) { var timeoutid = null; homecoming function() { cleartimeout(timeoutid); timoeoutid = settimeout(callback, time || 1); }; }

edit

the previous resets per call, utilize first click & ignore subsequent clicks

var throttleasync(callback, time) { var timeoutid = null; homecoming function() { if(timeoutid == null) { timoeoutid = settimeout(function() { timeoutid = null; callback; }, time || 1); } }; }

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
