So below i added code to template.js for one of my questions. You can click the [+] to add the row and the [-] shows up so its evident the code runs, but no rows are actually added or removed. How do I fix this (i am using limesurvey 2.5)? Thank you!
Code:
$(document).ready(function() {
// A function to add or remove rows of an Array (Multi Flexible)(Text) question
function varLengthArray(qID) {
/* from https://docs.limesurvey.org/tiki-index.php?page=Workarounds%3A+Manipulating+a+survey+at+runtime+using+Javascript&structure=English+Instructions+for+LimeSurvey#Variable_Length_Array_Multi_Flexible_Text_question
*/
if ($('#question'+qID+'').length > 0) {
// The HTML content of the Add/Remove elements - modify as you wish
var addContent = '[+]';
var removeContent = '[-]';
// Create the Add and Remove elements & insert them
var el1 = document.createElement('div');
el1.setAttribute('id','addButton'+qID);
document.body.appendChild(el1);
var el2 = document.createElement('div');
el2.setAttribute('id','removeButton'+qID);
document.body.appendChild(el2);
// Move them to after the array
$( 'div#addButton'+qID ).appendTo($( '#question' + qID + ' table.question' ).parent());
$( 'div#removeButton'+qID ).appendTo($( '#question' + qID + ' table.question' ).parent());
// Insert their HTML
$( 'div#addButton'+qID ).html( addContent );
$( 'div#removeButton'+qID ).html( removeContent );
// Style the elements - you can modify here if you wish
$( 'div#addButton'+qID ).css({
'margin':'10px 0 0 10px',
'padding':'1px',
'text-align':'center',
'font-weight':'bold',
'width':'auto',
'cursor':'pointer',
'float':'left'
});
$( 'div#removeButton'+qID ).css({
'margin':'10px 0 0 10px',
'padding':'1px',
'text-align':'center',
'font-weight':'bold',
'width':'auto',
'cursor':'pointer',
'float':'left'
});
// Initially hide the Remove element
$( 'div#removeButton'+qID ).hide();
// Call the functions below when clicked
$( 'div#addButton'+qID ).click(function (event) {
addRow(qID);
});
$( 'div#removeButton'+qID ).click(function (event) {
removeRow(qID);
});
// Function to add a row, also shows the Remove element and hides the
//Add element if all rows are shown
function addRow(qID) {
var arrayRow = '#question' + qID + ' table.question tbody';
var rowCount = $( arrayRow ).size() - 1;
$( arrayRow + '[name="hidden"]:first' ).attr('name', 'visible').show();
$( 'div#removeButton'+qID ).show();
if ( $( arrayRow + ':eq(' + rowCount + ')' ).attr('name') == 'visible' ) {
$( 'div#addButton'+qID ).hide();
}
}
// Function to remove a row, also clears the contents of the removed row,
// shows the Add element if the last row is hidden and hides the Remove
// element if only the first row is shown
function removeRow(qID) {
var arrayRow = '#question' + qID + ' table.question tbody';
var rowCount = $( arrayRow ).size() - 1;
$( arrayRow + '[name="visible"]:last input[type="text"]' ).val('');
$( arrayRow + '[name="visible"]:last' ).attr('name', 'hidden').hide();
$( 'div#addButton'+qID ).show();
if ( $( arrayRow + ':eq(1)' ).attr('name') == 'hidden' ) {
$( 'div#removeButton'+qID ).hide();
}
}
// Just some initialization stuff
var arrayRow = '#question' + qID + ' table.question tbody';
var rowCount = '';
// Initially hide all except first row or any rows with populated inputs
$( arrayRow ).each(function(i) {
if ( i > 0 ) {
// We also need to give the hidden rows a name cause IE doesn't
// recognize jQuery :visible selector consistently
$( this ).attr('name', 'hidden').hide();
$('input[type=text]', this).each(function(i) {
if ($(this).attr('value') !== '') {
$(this).parents('tbody:eq(0)').attr('name', 'visible').show();
$( 'div#removeButton'+qID ).show();
}
});
rowCount = i;
}
});
}
}
// Call the function with a question ID
varLengthArray(17);
});
