Improve this questionIn this project, there is one user input and results for that input will be taken form database. For each of the result, there will be disable button if zone_enable is 0. If zone_enable is 1 it will show as enable. Previously, I made with <a href> to run the script and if I click on the disable or enable button, the whole page got refresh but the it updates the database. I did some research and not to reload the page, I can try on with AJAX so I tested out. But I've never tryout Ajax and if I click on disable or enable, database is no more updating.
Below codes are from Javascript. `
function Submit(){
var productlotid = document.translot.productlotid.value;
if (productlotid == null || productlotid ==""){
alert("Lot ID should not be blank.");
return false;
}
document.getElementById("result").innerHTML = SynReqData(reqHttp2,'correlationwafer_result.php?productlotid=' + productlotid );
console.log(productlotid);
//alert ('Request Successful.');
//window.location.reload();
//return false;
}
