You can see in the paper form attached what I need to convert into a web form. I want it to show the check boxes and disable the input fields unless the user checks the box next to it. I've seen ways of doing this with one or two elements, but I want to do it with about 20-30 check/input pairs, and don't want to repeat the same code that many times. I'm just not experienced enough to figure this out on my own. Anyone know anywhere that explains how to do this? Thanks!
P.S. Eventually this data is all going to be sent through an email with PHP.
I don't think this is a good idea at all.
Think of the users. First they have to click to enter a value. So they always need to change their hand from mouse to keyboard. This is not very usable.
Why not just give the text-fields? When sending with email you could just leave out the empty values.
in your HTML :
//this will be the structure of each checkbox and input element.
<input type="checkbox" value="Public Relations" name="skills" /><input type="text" class="hidden"/> Public Relations <br/>
in your CSS:
.hidden{
display:none;
}
.shown{
display:block;
}
in your jQuery:
$('input[type=checkbox]').on('click', function () {
// our variable is defined as, "this.checked" - our value to test, first param "shown" returns if true, second param "hidden" returns if false
var inputDisplay = this.checked ? 'shown' : 'hidden';
//from here, we just need to find our next input in the DOM.
// it will always be the next element based on our HTML structure
//change the 'display' by using our inputDisplay variable as defined above
$(this).next('input').attr('class', inputDisplay );
});
Have fun.
Since your stated goal is to reduce typing repetitive code, the real answer to this thread is to get an IDE and the zen-coding plug in:

I have googled and looked throughout the whole documentation and could not figure out why value of input text is not shown. I am using FireFox latest version and below is what I have done so far.
<input name="amount" class="easyui-validatebox" id="d_amount" value="">
In regular html or php page we can give value="300" to set default value, but in EasyUI, it is not possible. So I was thinking possible alternative like below:
<script>
var m = '300';
document.getElementById("d_amount").value.innerHTML=m;
</script>
Nothing is shown and I am not getting any error. Any EasyUI expert, please help me.
NOTE: this input field is inside the dialog
To set the default value, you have to set the value attribute. However, that does not necessarily update the value property so you need to do both. So given:
<input name="amount" class="easyui-validatebox" id="d_amount" value="">
set the default value by setting the value attribute:
var input = document.getElementById('d_amount')
input.setAttribute('value', 'whatever');
now set the value property:
input.value = 'whatever';
Note that you can also get a reference to the input as a member of the form that it's in:
var input = document.formName.d_amount;
Use the below code
$("#d_amount").numberbox({
min:0,
precision:2,
value:300
})
Reference : numberbox
Or try this one
$("#d_amount").textbox({
buttonText:'Search',
iconCls:'icon-man',
iconAlign:'left',
value:"300"
});
Reference : textbox
use this code to set the value inside $(document).ready(function(){}
....
$("#d_amount").numberbox('setValue','300');
....
if still not working, just try to set name and id as the same name and id
<input name="d_amount" class="easyui-validatebox" id="d_amount" value="">
I am always working with this numberbox and it's working
I have found your thread because I am also having the same issue and I have just across this thing today. Your case is a little bit different (maybe) then my case because you want to set the default which can be changed by the user later (I believe). In my case, the value will be fixed (will not be changed) so I have applied a trick and hopefully it can give some ideas to you and others who are having same issue. Please refer below:
In first page says pageA.php:
<select name="myThing" id="myThing">
<option value="Your Desired Value" selected="selected">Something</option>
</select>
Still in the same page, under your $(document).ready( function(){ put the code below:
$("#myThing").val($("#myThing option:first").val());
That code is to make sure your desired value appears at the first row in the drop down. I say this because in EasyUI it seems when I use drop down and put single option, the first row will be blank and the second row will hold your input. So that is the trick to ensure your desired value appears on top and selected. Put the select under the form then during normal post, you will be able to get the value of it in the posted page. Enjoy. Thank you.
Suggestion: if your value can be changed by user, use placeholder and you can hide the default value from user using my trick.
try this
document.getElementById("d_amount").value=m;
you don't need innerHTML
I found the answer here. The trick is to use the code inside $(function(){});
$(function(){
var m=300;
$('#d_amount').textbox('setValue', m);
});
I too had this problem and it was solved using the following
First my input was in the form like this:
<input name="hostFirstName" id="hostFirstName" class="easyui-textbox">
I needed to load content from the db then pre-fill the input with this data so the user could edit the content.
I used the following javascript.
NOTE: i didn't hide this away inside an anonymous function() and it is working. I tested this first from the F12 console to make sure it was working before changing my code.
//populate with existing data
$('#hostFirstName').textbox('setValue', "Is this working?");
The docs on jeasyui.com don't provide this example when you look at the textbox api reference. But they do provide an example when looking at the combobox (http://www.jeasyui.com/documentation/index.php#) the combobox and textbox use the same setValue method.
Hopefully this works for you like it does for me.
My ultimate goal is to add some validation to a set of date fields. However, my javascript sucks, so I'm starting small.
I am starting out by trying to get an alert message when a user leaves a field.
(For simplicity I'm just doing it all in my view...) Heres what I go to work...
# html.erb-template
<div class="from_date">
From Date
<input type="text" id="from_date" name="from_date"></input>
</div>
<script>
$("#from_date").blur( function() {
alert("boom!");
});
</script>
Your code seems to be fine - problem is that class and id are named the same, but you want to watch the input field not the surrounding div.
I just made a fiddle from your script and changed
the listener to be attached to the input field's id - and it's working.
the alert into a console.log
see
$("#from_date").blur(function() {.....
// instead of
$(".from_date").blur(function() {.....
I have a couple of radios (#LocalDelivery and #StandardShip) related to a couple text inputs (#LocalDate and #datepicker). Then, off in another section is another text input with class productAttributeValue.
If LocalDelivery is chosen/checked, I need its input, #LocalDate to get the value and name from the input with class productAttributeValue. Or, if #StandardShip is chosen/checked I need its input, #datepicker, to get the value and name from the input with class productAttributeValue.
I have tried various combinations of the following:
if (!$('#LocalDelivery').is(":checked")) {
$('#datepicker').val("");
$('#LocalDate').val($('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').val());
$('#LocalDate').attr('name',
$('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').attr('name'));
}
if (!$('#StandardShip').is(":checked")) {
$('#LocalDate').val("");
$('#datepicker').val($('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').val());
$('#datepicker').attr('name',
$('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').attr('name'));
}
Per my other thread, Issue with jQuery 'else', this method isn't working. According to the answers given there, this is the wrong method entirely but I'm not sure how else to go about this.
Here is a fiddle:
This is my glorious Fiddle
EDIT:
Per beautifulcoder's comment I have added a click function to both radios. While it would be preferable for the inputs to populate their value without clicking first, this is the first solution I've had that works. Created a fiddle here, hope it helps someone else:
My amazing working Fiddle
I'm very new to jQuery and have been stumped by particular issue. I am dynamically adding 2 checkbox fields to a screen form using the code below:
var summon_search = "<br><br><br><label for='summon_search'>Search this resource from compatible products*</label><input type='checkbox' id='summon_search' >";
var summon_link = "<br><br><label for='summon_link'>Link direct from content items in compatible products*</label><input type='checkbox' name='summon_link'>";
$(summon_search+summon_link).insertAfter("#jstor_selection");
However I have had limited success when I want to remove these fields AND labels (which is dependant on another value) and replace them with new fields. The code below shows my best attempt so far. It does appear to remove the labels and first field, but for some reason the last field remains. Could someone please advise if they can spot anything I've done wrong, or perhaps supply a better example of handling this ?
if ($("#summon_search").length > 0 ) {
//Removal of Label and Field (Attempted)
$("label[for=summon_search]").remove();
$("label[for=summon_link]").remove();
$("#summon_search").remove();
$("#summon_link").remove();
Any feedback much appreciated.
Change name='summon_link' to id='summon_link', because #summon_link expects an id.
if you see your code the summon_link variable give it a id instead of name like in the summon_search variable
name=summon_link change it to id='summon_link'
if your intention is to add these HTML string after object with Id 'jstor_selection', you can use like this
$("#jstor_selection").append(summon_search+summon_link);
you should give the for= value in quotes.
EDIT: to remove extra <br>, normally it is suggested not to use <br>
$("label[for='summon_search']").prev('br').remove()
$("label[for='summon_link']").prev('br').remove()
$("label[for='summon_search']").remove();
$("label[for='summon_link']").remove();
also in the suman_link input element you have given as name
<input type='checkbox' name='summon_link'>
either change this to
<input type='checkbox' id='summon_link'/>
or
$("#summon_link").remove();
to
$("input[name='summon_link']").remove();
I need to clear the default values from input fields using js, but all of my attempts so far have failed to target and clear the fields. I was hoping to use onSubmit to excute a function to clear all default values (if the user has not changed them) before the form is submitted.
<form method='get' class='custom_search widget custom_search_custom_fields__search' onSubmit='clearDefaults' action='http://www.example.com' >
<input name='cs-Price-2' id='cs-Price-2' class='short_form' value='Min. Price' />
<input name='cs-Price-3' id='cs-Price-3' class='short_form' value='Max Price' />
<input type='submit' name='search' class='formbutton' value=''/>
</form>
How would you accomplish this?
Read the ids+values of all your fields when the page first loads (using something like jquery to get all "textarea", "input" and "select" tags for example)
On submit, compare the now contained values to what you stored on loading the page
Replace the ones that have not changed with empty values
If it's still unclear, describe where you're getting stuck and I'll describe more in depth.
Edit: Adding some code, using jQuery. It's only for the textarea-tag and it doesn't respond to the actual events, but hopefully it explains the idea further:
// Keep default values here
var defaults = {};
// Run something like this on load
$('textarea').each(function(i, e) {
defaults[$(e).attr('id')] = $(e).text();
});
// Run something like this before submit
$('textarea').each(function(i, e){
if (defaults[$(e).attr('id')] === $(e).text())
$(e).text('');
})
Edit: Adding some more code for more detailed help. This should be somewhat complete code (with a quality disclaimer since I'm by no means a jQuery expert) and just requires to be included on your page. Nothing else has to be done, except giving all your input tags unique ids and type="text" (but they should have that anyway):
$(document).ready(function(){
// Default values will live here
var defaults = {};
// This reads and stores all text input defaults for later use
$('input[type=text]').each(function(){
defaults[$(this).attr('id')] = $(this).text();
});
// For each of your submit buttons,
// add an event handler for the submit event
// that finds all text inputs and clears the ones not changed
$('input[type=submit]').each(function(){
$(this).submit(function(){
$('input[type=text]').each(function(){
if (defaults[$(this).attr('id')] === $(this).text())
$(this).text('');
});
});
});
});
If this still doesn't make any sense, you should read some tutorials about jQuery and/or javascript.
Note: This is currently only supported in Google Chrome and Safari. I do not expect this to be a satisfactory answer to your problem, but I think it should be noted how this problem can be tackled in HTML 5.
HTML 5 introduced the placeholder attribute, which does not get submitted unless it was replaced:
<form>
<input name="q" placeholder="Search Bookmarks and History">
<input type="submit" value="Search">
</form>
Further reading:
DiveintoHTML5.ep.io: Live Example... And checking if the placeholder tag is supported
DiveintoHTML5.ep.io: Placeholder text
1) Instead of checking for changes on the client side you can check for the changes on the client side.
In the Page_Init function you will have values stored in the viewstate & the values in the text fields or whichever controls you are using.
You can compare the values and if they are not equal then set the Text to blank.
2) May I ask, what functionality are you trying to achieve ?
U can achieve it by using this in your submit function
function clearDefaults()
{
if(document.getElementById('cs-Price-2').value=="Min. Price")
{
document.getElementById('cs-Price-2').value='';
}
}
