Simple JS fiddle containing my code in working state
I have a jQuery UI Autocomplete field, with a Dropdown button attached. It works floorlessly, however - its kinda annoying you have to manually delete the words inside the field for a search.
I am unsure if jQuery UI has a feature for it, unless i'd love to know.
I've tried to use onClick functions with JS, however since my field is not exactly an "form field" I've got kinda lost here.
My goal is to: reset the text field when a user presses it.It has prewritten text in it "Please select (Or Type)"
my cshtml file looks as following
cshtml
And it looks like this on the browser browser
Code for Image 1:
<select asp-for="Dinosaur" class="combobox" id="dinoType" asp-items="Html.GetEnumSelectList<Dinosaurs>()">
<option selected="selected" type="text" onclick="resetText()" value="0">Please select (Or Type)</option>
</select>
<span asp-validation-for="Dinosaur" class="text-dark" />
As you can see it has the text in, which i have to CTRL + A, DELETE before i can search in my field.
A function to clear this text when a user presses it will easen the pressure.
I might just be stupid to see the simple solution, i just feel like I've tried some of the things that I'd believe would work. (As the onclick="ResetText()" with a JS code attached to it)
When I click on drop down this is what showing.
Best Regards,
You don't want to wire an onclick listener on your option element, you want an onchange event listener on your select element. onclick is not supported on option elements.
use onchange instead of using onclick and this action should be on the select tag. not on the options. Try this example.
$('select').on('change', function() {
if (this.value === 'disabled') {
this.value = '';
}
console.log(this.value);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select asp-for="Dinosaur" class="combobox" id="dinoType" asp-items="Html.GetEnumSelectList<Dinosaurs>()">
<option selected="selected" type="text" value="disabled">Please select (Or Type)</option>
<option type="text" value="One">One</option>
<option type="text" value="two">two</option>
</select>
<span asp-validation-for="Dinosaur" class="text-dark" />
I have a project in which I must do something like this:
when a user's page loads, he gets a personalized select box (with some options generated by PHP for him) and then, when he changes the option, I must change the rest of the content (on the same page).
for example, let the select box for a kind of user be:
Main content
Tools
Now, my idea was to have a
<form action="processing.php">
<select name="choice" onChange="submit();"> etc. which should pass the user's choice to processing.php. The problem is, I want the first option to be automatically selected and the content for that option to appear when the page loads - somehow like the first option to be automatically submitted.
Also, different kind of users should get different options, and I thought I can use a single page to process these requests. Is this achievable?
Can you please help me with an idea on how to submit that form automatically with the first generated option? Thank you.
You can use the onChange Event of the selection. In the handler you can then do the redirect
let sel = document.getElementById('yourselect');
let form = document.getElementById('yourform');
sel.onchange = function() {
form.submit()
}
You can easily bind the select change with Javascript. Here is the example with jQuery:
$('#mySelect').on('change', function(){
// Do your staff
$('#myForm').submit();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<select id="mySelect" method="post" action="processing.php" name="select_name">
<option value="">Select One</option>
<option value="http://google.com">Google</option>
</select>
</form>
I'm trying to add a HTML link to an input box using the following jQuery:
var E = "<a class='tagged_person' contenteditable='false' href='http://www.google.com'>Click This</a>";
$("input[name='newComment']").val(E);
Which is working, but its literally displaying the <a href..., which is what I wanted backend wise, but on the frontend, I'd like the user to see it as rendered as a HTML <a> link. Just like on Facebook/Twitter you can tag users and then there's a link.
I think you're looking for the JQuery method .append. That lets you pass a string of HTML and have it parsed into the DOM. Check it out here
For example:
$('#myDiv').append('Search for it!');
There's also .appendTo() if it suits your aesthetic better.
Edit: If you're trying to literally stick html as the value of a text input, you can't do that. <input type="text"> carry text, and that's it. You'd have to make your own input form, or use a JQuery plugin. Why would you want to have a link in a form input anyway though? Sure, you could have the user redirected when clicking the form through different event handlers, but input is for inputting. If it redirects, then you didn't really want an input in the first place.
You can use the following code, which when select it will open the link in a new window.
<form action="../">
<select name="myDestination">
<option value="http://www.website1.com/">Website 1</option>
<option value="http://www.google.com/">GOOGLE</option>
</select>
<input type="button"
value="Open in New Window!"
onclick="ob=this.form.myDestination;window.open(ob.options[ob.selectedIndex].value)">
</form>
Or without the need to press a button:
<form action="../">
<select onchange="window.open(this.options[this.selectedIndex].value,'_top')">
<option value="">Choose a destination...</option>
<option value="http://www.website1.com/">Website 1</option>
<option value="http://www.google.com/">GOOGLE</option>
</select>
</form>
Also created a jsfiddle to demonstrate: jsFiddle
I have dynamically created option elements with javascript. I double click an option from one select field to transfer it to a second, disabled, multiple select field. This works fine. The problem appears when I go to submit the form with the new information. The second select field is not passed to PHP. I'm assuming it thinks its empty, but each of the options I added are selected by default and I visually see them all there. I've been looking around for a solution to this, but am having little luck. Everything I can find says that the most likely cuprit is a browser incompatibility or that the elements are not being added to the form. If it is a browser incompatibility issue, I've tried it on all the major browsers all with the same results, so I would like to know which one I'm missing (FF, Chrome, IE). As for not being added to the form, I don't see how that could be possible. The select element already exists in the form and I am merely appending new options in it. Am I missing something, or is this just not possible?
<script type="text/javascript" language="JavaScript">
function addModule(value, title) {
modules = document.getElementById('modules');
modules.options[modules.options.length] = new Option(title, value, true);
}
</script>
<form name="addModules" method="POST" action="submit.php">
<select name="moduleList" size="20" ondblclick="addModule(this.options[this.selectedIndex].text, this.value);">
<?php //dynamically created options from PHP ?>
</select>
<select id="modules" name="modules[]" multiple="multiple" size="20" DISABLED></select>
<input type="submit" value="Add Modules" />
</form>
Disabled fields are not submitted. The easiest solution is to change it to readonly. If you're determined to have it as disabled, you could make a hidden field that is updated with values from it, but I strongly suggest just using readonly and then trying to style it as desired.
It's because the second select is disabled, it's data doesn't get sent when the form is submitted.
You could try making it readonly instead of disabled.
This is the standard browser behavior. While adding the values to the disabled select list, you can also add it to a hidden input field, and then access this in the posted request.
I have a select form field that I want to mark as "readonly", as in the user cannot modify the value, but the value is still submitted with the form. Using the disabled attribute prevents the user from changing the value, but does not submit the value with the form.
The readonly attribute is only available for input and textarea fields, but that's basically what I want. Is there any way to get that working?
Two possibilities I'm considering include:
Instead of disabling the select, disable all of the options and use CSS to gray out the select so it looks like its disabled.
Add a click event handler to the submit button so that it enables all of the disabled dropdown menus before submitting the form.
Disable the fields and then enable them before the form is submitted:
jQuery code:
jQuery(function ($) {
$('form').bind('submit', function () {
$(this).find(':input').prop('disabled', false);
});
});
<select disabled="disabled">
....
</select>
<input type="hidden" name="select_name" value="selected value" />
Where select_name is the name that you would normally give the <select>.
Another option.
<select name="myselect" disabled="disabled">
<option value="myselectedvalue" selected="selected">My Value</option>
....
</select>
<input type="hidden" name="myselect" value="myselectedvalue" />
Now with this one, I have noticed that depending on what webserver you are using, you may have to put the hidden input either before, or after the <select>.
If my memory serves me correctly, with IIS, you put it before, with Apache you put it after. As always, testing is key.
I`ve been looking for a solution for this, and since i didnt find a solution in this thread i did my own.
// With jQuery
$('#selectbox').focus(function(e) {
$(this).blur();
});
Simple, you just blur the field when you focus on it, something like disabling it, but you actually send its data.
I faced a slightly different scenario, in which I only wanted to not allow the user to change the selected value based on an earlier selectbox. What I ended up doing was just disabling all the other non-selected options in the selectbox using
$('#toSelect').find(':not(:selected)').prop('disabled',true);
it dows not work with the :input selector for select fields, use this:
jQuery(function() {
jQuery('form').bind('submit', function() {
jQuery(this).find(':disabled').removeAttr('disabled');
});
});
Same solution suggested by Tres without using jQuery
<form onsubmit="document.getElementById('mysel').disabled = false;" action="..." method="GET">
<select id="mysel" disabled="disabled">....</select>
<input name="submit" id="submit" type="submit" value="SEND FORM">
</form>
This might help someone understand more, but obviously is less flexible than the jQuery one.
The easiest way i found was to create a tiny javascript function tied to your form :
function enablePath() {
document.getElementById('select_name').disabled= "";
}
and you call it in your form here :
<form action="act.php" method="POST" name="form_name" onSubmit="enablePath();">
Or you can call it in the function you use to check your form :)
I use next code for disable options in selections
<select class="sel big" id="form_code" name="code" readonly="readonly">
<option value="user_played_game" selected="true">1 Game</option>
<option value="coins" disabled="">2 Object</option>
<option value="event" disabled="">3 Object</option>
<option value="level" disabled="">4 Object</option>
<option value="game" disabled="">5 Object</option>
</select>
// Disable selection for options
$('select option:not(:selected)').each(function(){
$(this).attr('disabled', 'disabled');
});
Just add a line before submit.
$("#XYZ").removeAttr("disabled");
Or use some JavaScript to change the name of the select and set it to disabled. This way the select is still submitted, but using a name you aren't checking.
I whipped up a quick (Jquery only) plugin, that saves the value in a data field while an input is disabled.
This just means as long as the field is being disabled programmaticly through jquery using .prop() or .attr()... then accessing the value by .val(), .serialize() or .serializeArra() will always return the value even if disabled :)
Shameless plug: https://github.com/Jezternz/jq-disabled-inputs
Based on the solution of the Jordan, I created a function that automatically creates a hidden input with the same name and same value of the select you want to become invalid. The first parameter can be an id or a jquery element; the second is a Boolean optional parameter where "true" disables and "false" enables the input. If omitted, the second parameter switches the select between "enabled" and "disabled".
function changeSelectUserManipulation(obj, disable){
var $obj = ( typeof obj === 'string' )? $('#'+obj) : obj;
disable = disable? !!disable : !$obj.is(':disabled');
if(disable){
$obj.prop('disabled', true)
.after("<input type='hidden' id='select_user_manipulation_hidden_"+$obj.attr('id')+"' name='"+$obj.attr('name')+"' value='"+$obj.val()+"'>");
}else{
$obj.prop('disabled', false)
.next("#select_user_manipulation_hidden_"+$obj.attr('id')).remove();
}
}
changeSelectUserManipulation("select_id");
I found a workable solution: remove all the elements except the selected one. You can then change the style to something that looks disabled as well.
Using jQuery:
jQuery(function($) {
$('form').submit(function(){
$('select option:not(:selected)', this).remove();
});
});
<select id="example">
<option value="">please select</option>
<option value="0" >one</option>
<option value="1">two</option>
</select>
if (condition){
//you can't select
$("#example").find("option").css("display","none");
}else{
//you can select
$("#example").find("option").css("display","block");
}
Another option is to use the readonly attribute.
<select readonly="readonly">
....
</select>
With readonly the value is still submitted, the input field is grayed out and the user cannot edit it.
Edit:
Quoted from http://www.w3.org/TR/html401/interact/forms.html#adef-readonly:
Read-only elements receive focus but cannot be modified by the user.
Read-only elements are included in tabbing navigation.
Read-only elements may be successful.
When it says the element may be succesful, it means it may be submitted, as stated here: http://www.w3.org/TR/html401/interact/forms.html#successful-controls
