Preview Did Not Work – The solution

I figured out that the preview didn’t work if you are blocking popups in your browser (for me on Safari where no message appears like Firefox do).

This has to do with your window.open call in ebs_main.js on line 249. The window.open call need to be called from an event initiated by the user, which is not the case here, because it’s called within the ajax call.

I changed your the code

jQuery('.ebsp-preview-button').click(function(){
    var $this=jQuery(this);
    $this.parent().find('.spinner').show();
    var shortcode=eval(pluginObj.pluginName+'_generate_shortcode(pluginObj,form,table)');
    jQuery.ajax({
        url:ebs_ajaxurl,
        type:'post',
        data:{
            action:'ebs_set_preview_content',
            shortcode:shortcode
        },
        success:function(res){
            $this.parent().find('.spinner').hide();
            var  win= window.open(ebs_preview_page_path,'osc_ebs_pro');
            if (window.focus)
            {
                win.focus();
            }
        }
    });
})

to this

jQuery('.ebsp-preview-button').on('click', function(){
    var preview_path = ''
    var $this=jQuery(this);
    $this.parent().find('.spinner').show();
    var shortcode=eval(pluginObj.pluginName+'_generate_shortcode(pluginObj,form,table)');
    jQuery.ajax({
        url:ebs_ajaxurl,
        type:'post',
        data:{
            action:'ebs_set_preview_content',
            shortcode:shortcode
        },
        success:function(res){
            $this.parent().find('.spinner').hide();
            preview_path = ebs_preview_page_path;
        }
    });
    var win = window.open(ebs_preview_page_path,'osc_ebs_pro');
    if (window.focus)
    {
        win.focus();
    }
})

and it worked still if the browser is set to block popup windows.

As you can see I saved the ebs_preview_page_path within the ajax call and put the window.open call out of the ajax directly into the .on(‘click’) event. That’s the whole trick.

Hope this helps to make the plugin work for everyone.
