在Javascript中录制按钮ID

Question

I am trying to create an item selection menu, where the user is presented with multiple buttons to pick their choices. I am creating several divs with PHP.

     <div id="h1-1"><input type="button" value="h1-1" onclick="recordValue()"></div>
     <div id="h1-2"><input type="button" value="h1-2" onclick="recordValue()"></div>

I would like to record all the values of buttons pressed and show these values via Ajax. Then when user is done selecting and presses submit I will insert these into MSSQL database.

• How do I record button values to an array with Javascript?
• How do I then show what was pressed?
• Where could I execute some filtering of the selections (e.g. if h1-1 was pressed i do not want them to be able to select h2-1) ?

Answer 1

I would keep the value in an array.
change you onclick part to
onclick="recordValue(this)"
and create an array outside the scope of the recordValue function wherever you declare it

var values = [];
function recordValue(element) {
    values.push(element.value);
    // code here to display value somewhere on the page
}

and then somewhere listen for the form's submit event and then send the data in your array via ajax to your server.
