Hello community Stackoverflow,
i recently begun again to make some experiments with web developing and I would appreciate it, if you could help me with the following issue:
I'm trying to save the string of each input in the following pictured form in a database, after the mouse cursor had left the textBox (OnLeave), this string will be called from the database, after the user clicked on the button "save". I need to check this string before the data being saved after clicking on "save"
Exemple:
step 1: a user types his Name = 'Stackoverflower' in the inputfield and then moves the mouse cursor outside the the inputfiel;
step 2: by leaving the inputfiel occurs the following event, in the background: a php code will save that input (the name: 'Stackoverflower') in the database;
step 3: after the user clicked on the button "save", a php code will call that string 'Stackoverflower';
That is a solution, but I don't want to save any data in the database unless the user clicks "save". So how can I save that input temporarily (not in the database - maybe in a hidden dom element ? Or do you maybe have a better idea?).
I'll appreciate your interaction
Friendly regards Reda
PHP only executes on page load, to do this, you will need to use Ajax to execute the save PHP script.
To store the value, you can use a variable.
let fname; // declare the fname value
let lname; // declare the lname value
let bday; // declare the bday value
function mouseLeft() {
fname = document.getElementById('fname').value; // store the first name value
lname = document.getElementById('lname').value; // store the last name value
bday = document.getElementById('bday').value; // store the birthday value
//optional:
document.getElementById('storedvalues').innerText = "fname=" + fname + ", lname=" + lname + ", bday=" + bday;
// your ajax script goes here with fname, lname and bday being the values of their respective inputs
