Question

Use Ajax to call PHP function for HTML button Onclick

Answer 1

+1 A:

Using jQuery (untested):

function PrintDist() {
    var submitButton = $(this).find('*:submit');

    $.post(this.action, $(this).serialize(), function() {
        alert('Form submitted!');
        submitButton.attr('disabled', 'false').attr('value', 'Enter');
    });

    submitButton.attr('disabled', 'true').attr('value', 'Posting...');

    return false;
}

Use a proper form as your HTML (for people without Javascript, and for the script to work nicely):

<form action="xxx" method="post" onsubmit="return PrintDist()">
    <input text="text" name="airport1" id="airport1" />
    <input text="text" name="airport2" id="airport2" />
    <input type="submit" value="Enter" />
</form>

A:

Use any javascript library to make ajax calls to the php script on the server. For example:

nice peace of code but how would you pass a function parameter

<input type="button" value="Enter" onclick=PrintDist(30)/>

function PrintDist($value){ foo else bar }
