So, here's my script:
$(function () {
// define this here because we're changing the ID
var $twitter = $('twitter');
// bind to select inside iframe
$('#iframe').on('load', function () {
$(this).contents().find('#cds').change(function () {
var selectVal = $(this).val();
url = 'https://twitter.com/intent/tweet?button_hashtag=stream&text=Just enjoying ' + selectVal + ' on';
$twitter.attr("id", url);
}).change(); // trigger change to get initial value
});
});
Basically, it takes the selected value from my select box, and outputs it into a twitter link. The problem is, when nothing is selected, it outputs "null", and I was wondering if there was a way to detect this, and echo something else.
Try this:
var selectVal = $(this).val() || 'default value';

i need to show searching value from alert when click on 'no_results_text' if it's not available on the list.
i have put and on click method as 'no_results_text', so i need that typed value in alert
window.onload = function () {
$('#secondary_diagnosis').chosen({no_results_text: '<a onclick="add_new_diagnosis()">Save as New </a>'});
}
function add_new_diagnosis() {
alert($('#secondary_diagnosis input').val());
}```
window.onload = function () {
$('#secondary_diagnosis').chosen({no_results_text: '<a onclick="add_new_diagnosis()">Save as New </a>'});
}
in the window.onload you can set the onclick funtion to the default value to the chosen. after click it, you can get that typed value like this.
var new_value = $('.chosen-results .no-results span').text();
aleart('typed value is : '+ new_value);
I have a select field ('5f01264e722ae') with which I would like to change the color of a text print ('.sw_poster_text2'). With a little help from another member, I uploaded the script below. However, as soon as I undo the // from the .change function my website no longer displays the print, image on which to print, and then select options. Any idea how to fix this? Here is a link of the working page: https://www.horseglamour.com/product/pagony-concours-zadeldek/
Thank you for your help.
<script>
jQuery(document).ready(function() {
var fieldId = "5f0124e773aa8"; // Change this
var defaultText = "my name"; // Change this
if (!jQuery('input[data-field-id="' + fieldId + '"]').length)
return;
var $el = jQuery('<div class="sw_poster_text2">').html(defaultText);
$el.appendTo(jQuery('.woocommerce-product-gallery--with-images'));
jQuery(document).on('change keyup', 'input[data-field-id="' + fieldId + '"]', function() {
var v = jQuery(this).val() || defaultText;
jQuery('.sw_poster_text2').html(v);
}).trigger('change');
//$("select[data-field-id='5f01264e722ae']").change(function() {
//var color = $(this).find('option:selected').data('wapf-label')
//$(".sw_poster_text2").css("color", color);
//});
});
</script>
You can alter commented out part of your script to following:
jQuery("select[data-field-id='5f01264e722ae']").change(function() {
var color = jQuery(this).find('option:selected').data('wapf-label')
jQuery(".sw_poster_text2").css("color", color);
});
or if you perfer $ to access jQuery you can reference to it in callback https://api.jquery.com/jquery.noconflict/
jQuery(document).ready(function($) {
var fieldId = "5f0124e773aa8"; // Change this
var defaultText = "my name"; // Change this
if(!jQuery('input[data-field-id="'+fieldId+'"]').length)
return;
var $el = jQuery('<div class="sw_poster_text2">').html(defaultText);
$el.appendTo(jQuery('.woocommerce-product-gallery--with-images'));
jQuery(document).on('change keyup','input[data-field-id="'+fieldId+'"]',function(){
var v = jQuery(this).val() || defaultText;
jQuery('.sw_poster_text2').html(v);
}).trigger('change');
$("select[data-field-id='5f01264e722ae']").change(function() {
var color = $(this).find('option:selected').data('wapf-label')
$(".sw_poster_text2").css("color", color);
});
});
I am trying to filter one dropdown from the selection of another in a Rails 4 app with jquery. As of now, I have:
$(document).ready(function(){
$('#task_id').change(function (){
var subtasks = $('#subtask_id').html(); //works
var tasks = $(this).find(:selected).text(); //works
var options = $(subtasks).filter("optgroup[label ='#{task}']").html(); // returns undefined in console.log
if(options != '')
$('#subtask_id').html(options);
else
$('#subtask_id').empty();
});
});
The task list is a regular collection_select and the subtask list is a grouped_collection_select. Both which work as expected. The problem is that even with this code listed above I can't get the correct subtasks to display for the selected task.
NOTE: I also tried var tasks=$(this).find(:selected).val() that return the correct number but the options filtering still didn't work.
Try something like this instead (untested but should work).
$(function () {
var $parent = $('#task_id'),
$child = $('#subtask_id'),
$cloned = $child.clone().css('display', 'none');
function getParentOption() {
return $parent.find('option:selected');
}
function updateChildOptions($options) {
$child.empty();
$child.append($options);
}
$parent.change(function (e) {
var $option = getParentOption();
var label = $option.prop('value'); // could use $option.text() instead for your case
var $options = $cloned.find('optgroup[label="' + label + '"]');
updateChildOptions($options);
});
});
I have a modal box in jQuery which I have created to display some embed code. I want the script to take the id of the link that is clicked but I can't seem to get this working.
Does anyone know how I can do that or why this may be happening?
My jQuery code is:
function generateCode() {
var answerid = $('.openembed').attr('id');
if($('#embed input[name="comments"]:checked').length > 0 == true) {
var comments = "&comments=1";
} else {
var comments = "";
}
$("#embedcode").html('<code><iframe src="embed.php?answerid=' + answerid + comments + '" width="550" height="' + $('#embed input[name="size"]').val() + '" frameborder="0"></iframe></code>');
}
$(document).ready(function () {
$('.openembed').click(function () {
generateCode();
var answerid = $('.openembed').attr('id');
$('#box').show();
return false;
});
$('#embed').click(function (e) {
e.stopPropagation()
});
$(document).click(function () {
$('#box').hide()
});
});
My mark-up is:
Embed
Embed
Your problem is here:
$('.openembed')
returns an array of matched elements. Your should instead select only the clicked element.
$('.openembed') works correctly if you assing a click event to all elements that have this class. But on the other hand, you're unable do know which is clicked.
But fortunately in the body of handler function click you could call $(this).
$(this) will return the current (and clicked element).
// var answerid = $('.openembed').attr('id'); // Wrong
var answerid = $(this).attr('id'); // Correct
// Now you can call generateCode
generateCode(answerid);
Another error is the body of generateCode function. Here you should pass the id of selected element. This is the correct implementation.
function generateCode(answerid) {
if($('#embed input[name="comments"]:checked').length > 0 == true) {
var comments = "&comments=1";
} else {
var comments = "";
}
$("#embedcode").html('<iframe src="embed.php?answerid=' + answerid + comments + '" width="550" height="' + $('#embed input[name="size"]').val() + '"frameborder="0"></iframe>');
}
Here I have implemented your code with the correct behavior: http://jsfiddle.net/pSZZF/2/
Instead of referencing the class, which will grab all members of that class, you need to reference $(this) so you can get that unique link when it is clicked.
var answerid = $(this).prop('id');
$('.openembed').click(function () {
generateCode();
var answerid = $(this).attr('id');
$('#box').show();
return false;
});
Use $(this). $('.openembed') refers to multiple links.
var answerid = $('.openembed').attr('id');
needs to be
var answerid = $(this).prop('id');
The other answers are trying to fix the click() function, but your issue is actually with the generateCode function.
You need to pass the clicked element to the generateCode function:
$('.openembed').click(function () {
generateCode(this);
And modify generateCode:
function generateCode(element) {
var answerid = element.id;
Of course var answerid = $('.openembed').attr('id'); within the click code isn't correct either, but it doesn't seem to do anything anyway.
Get the id when the correct anchor is clicked and pass it into your generateCode function
$('.openembed').click(function () {
var answerid = $(this).attr('id');
generateCode(answerid)
$('#box').show();
return false;
});
Change your function
function generateCode(answerid) {
// dont need this line anymore
// var answerid = $('.openembed').attr('id');
I'm using the following placeholder plugin

It applies the placeholder attribute to form fields in browsers that do not natively support the placeholder attribute (ex. IE9). It works for statically loaded text fields, however for text fields that are loaded via ajax, the placeholder does not appear.
Is it possible to achieve this 'watermark' effect on text fields that are loaded via ajax?
What happens if you trigger the window resize function after adding in new inputs?
$(window).trigger('resize')
You could apply the plugin to newly created controls after the AJAX call completes. Forgive the pseudo-code as I'm not really sure about how your AJAX calls are working:
$.ajax({
url: "test.html",
cache: false
}).done(function( result ) {
field = $('<input>').html(result);
$("#results").append(field);
field.placeholder();
});
Another option is that you could use jQuery's .on() method to bind dynamically created controls to the function--but it wants an event (like click). I'm not sure how you would do that. Maybe something like this:
$( 'body' ).on('click','input.addField', function(e){
$(this).placeholder();
});
I know this won't work, but maybe it helps get you brainstorm solutions.
