How can I use input Box ID from PHP to JavaScript?

Question

My JavaScript function works fine, but I have problems getting different ids from the PHP input box.

JavaScript

window.onload = function()
{   
new JsD         


        

Answer 1

It's most likely with JsDatePick widget. Its target parameter takes a single ID of an element, therefore you'd have to wrap the JS code in a loop and initiate a separate instance of the widget for each field ID.

Assuming your input field indexing starts with 1:

window.onload = function()
{   
    var i = <?=$totalNumberOfInputs;?>

    for(j=1;j<=i;j++) {  
        new JsDatePick({
            useMode:2,
            target:"inputField" + j, //HERE I WOULD LIKE TO PASS DIFFERENT ID ex. "inputField1" + j
            dateFormat:"%Y-%M-%d",
            yearsRange:[1978,2120],
            limitToToday:false,
            cellColorScheme:"beige",
            imgPath:"main/img/",
            weekStartDay:1
        });
    }
}

You don't need to put the + sign to concatenate strings within double quotes (it's dot, by the way).

Answer 2

 //this is doesn't work 
echo "<input type=\"text\" class='textboxsize' id= \"inputField$k\" name=\"start_date[]\" value=\"$start_date\" />";

just remove that + sign.

Answer 3

Change:

id= \"inputField+$k\" name=...

To:

id=\"inputfield$k\" name=...

What is screwing it up is the "+" sign. PHP uses "." to concatenate strings. ECHO out $k properly and you shouldn't have any trouble
