  • 0

i am dynamically building a page. This page needs to read information from input tags but it is dynamic. Should i set up stuff to be an array since i am looking at

I want to preserve datasets.

<script>
   function adjustPilots(){
var pilots = $("#numPilots").val();
var info = '<td><table>'+
    '<tr><td>Minumum Collateral</td><td colspan="2"><input type = "text" size = "10" maxLength = "6" /> to <input type = "text" size = "10" maxLength = "6" /></td></tr>'+
    '<tr><td>Reward</td><td colspan="2"><input type = "text" size = "10" maxLength = "6" /> to <input type = "text" size = "10" maxLength = "6" /></td></tr>'+
    '<tr><td>Volume</td><td colspan="2"><input type = "text" size = "10" maxLength = "7" /> to <input type = "text" size = "10" maxLength = "7" /></td></tr>'+
    '<tr><td>Start: </td><td><input type = "text" name = "s" id = "s" class = "s" value autocomplete = "off"></td></tr>'+
    '<tr><td>End: </td><td><input type = "text" name = "e" id = "e" class = "e" value autocomplete = "off"></td></tr>'+
    '</table></td>';


for(var i = 0; i < Number(pilots); i++){
    $("#pilotrow").append(info);
}
}
</script>
<body>
<form>
<table>
<tr><td>Number of Pilots</td><td colspan="2"><input id = "numPilots" type = "text" size="3" maxLength="3" onchange = 'adjustPilots()' /></td></tr>
<tr id = "pilotrow"></tr>

<tr><td><input type = "submit" name = "submit"></td></tr>
</table>
</form>
</body>

An option i was thinking was to just not use a form, and build it with javascript. Then make a JSON object and use AJAX to send it to the server. Is that a solid way of doing it, or is there a better idea?

    There are at least 2 way to do that.

    Without javascript, you cate a form with array of element like this

    <input type="text" name="input[]"/>
<input type="text" name="input[]"/>
<input type="text" name="input[]"/>
<input type="text" name="input[]"/>

    in php

    $inputs = $_POST['input'];
for($inputs as $inp){

}

    With ajax and jquery, you can just simply serialize your form and post to backend
