In the graphic provided, there is a battlefield page featuring 20 users. To capture and store this data in a MySQL database, I have created a JavaScript script. However, an issue arises when trying to collect data from the next page after clicking "next" to load more users.
When the Ajax call fetches the next set of 20 users, the script fails to log the new information because the page does not fully reload during an Ajax call, preventing the script from executing. Is there a method to force a page reload when clicking the Ajax link?
Below is the code snippet:
grabData(); var nav = document.getElementsByClassName('nav')[0].getElementsByTagName('td')[2].getElementsByTagName('a')[0];
nav.addEventListener("click", function(){
grabData();
});
function grabData(){
var rows = document.getElementsByClassName('table_lines battlefield')[0].rows;
var sendData = '';
for(i=1; i < rows.length -1 ; i++){
var getSid = document.getElementsByClassName('table_lines battlefield')[0].getElementsByTagName('tr')[i].getElementsByTagName('td')[2].getElementsByTagName('a')[0].href;
var statsID = getSid.substr(getSid.indexOf("=") + 1); //Grabs ID out of stats link
var name = document.getElementsByClassName('table_lines battlefield')[0].getElementsByTagName('tr')[i].getElementsByTagName('td')[2].textContent.replace(/\,/g,"");
var tff = document.getElementsByClassName('table_lines battlefield')[0].getElementsByTagName('tr')[i].getElementsByTagName('td')[3].textContent.replace(/\,/g,"");
var rank = document.getElementsByClassName('table_lines battlefield')[0].getElementsByTagName('tr')[i].getElementsByTagName('td')[6].textContent.replace(/\,/g,"");
var alliance = document.getElementsByClassName('table_lines battlefield')[0].getElementsByTagName('tr')[i].getElementsByTagName('td')[1].textContent.trim();
var gold = document.getElementsByClassName('table_lines battlefield')[0].getElementsByTagName('tr')[i].getElementsByTagName('td')[5].textContent.replace(/\,/g,"");
if(alliance == ''){
alliance = 'None';
}
if(gold == '??? Gold'){
gold = 0;
}else{
gold = gold.replace(/[^\/\d]/g,'');
}
sendData += statsID + "=" + name + "=" + tff + "=" + rank + "=" + alliance + "=" + gold + "@";
}
$.ajax({
// you can use post and get:
type: "POST",
// your url
url: "url",
// your arguments
data: {sendData : sendData},
// callback for a server message:
success: function( msg ){
//alert(msg);
},
// callback for a server error message or a ajax error
error: function( msg )
{
alert( "Data was not saved: " + msg );
}
});
}
Therefore, this script fetches the information and sends it to a PHP file on the backend. When I navigate to the next page on the battlefield, I need to trigger this script again.
UPDATE: Issue Resolved. By locating the "next" anchor tag within the DOM tree, I was able to add an event listener that re-executes the JavaScript every time it is clicked.
