d3js (both v4 and also v3) charts in Drupal 7 with having click event attached to one of the svg text element using .attr("class", "ajax_button") and attaching Drupal behavior for that element. Problem is that click event is lost once tree gets collapsed and not get reattached on expand.
link : d3js + Drupal behavior
following is code for click element
(function($) {
Drupal.behaviors.listload = {
attach: function(context, settings) {
if (context == document) {
$('.ajax_button', context).once(function() {
$(this).click(function(e) {
e.preventDefault();
// https://stackoverflow.com/a/1369080
// to prevent collapsible function which is attached to parent element
e.stopPropagation();
var the_id = $(this).attr('href'); // contextual filter(nid) to views
noSlashes = the_id.replace(/\//g, '');
$.ajax({
url: Drupal.settings.basePath + 'views/ajax',
type: 'post',
data: {
view_name: 'candidate_list_er', //view name
view_display_id: 'candidate_list_block', //your display id
view_args: noSlashes, // your views arguments, //view contexuall filter
},
dataType: 'json',
success: function(response) {
//console.log(response);
if (response[1] !== undefined) {
//console.log(response[1].data); // do something with the view
var viewHtml = response[1].data;
$('#ajax-target .content').html(viewHtml);
//Drupal.attachBehaviors(); //check if you need this.
}
},
error: function(data) {
alert('An error occured!');
}
});
}); //click ends
}); //once ends
}
},
detach: function(context, settings, trigger) { //this function is option
$('.ajax_button').unbind(); //or do whatever you want;
}
};
})(jQuery);
