I have a chat that sends data to the database, I want to load each time the last message not all so on each message I gave it an id that I want to retrieve with .attr see code but .attr referral that 1
setInterval("load()", 5000);
function load(){
var last = $('#last_message span:last').attr('id');
if(last> 0){
$.ajax({
url : '/ajax/public_load.php?id_m=' + last,
type : 'GET',
dataType : "html",
success : function(data){
$("#last_p").append(data);
}
});
}
};<div class="" id="last_message">
<span id="<?=$public->chat_id?>" class="summary" style="margin-top: -11px;">
<?= $public->contenu ?>
</span>
</div></div>
The function attr return a string (the id of the tag), when you try to compare the id with a number javascript try to cast the value "chat_id?>" and obtains a NaN, the result of compare NaN > 0 is false, the code of condition will not be executed.
