I am currently working with the Laravel Framework and I am working on a webpage that will allow a user to enter a start and end date in order to search through lists of tasks (by that filter). So far, a user can decide from a dropdown list if the date is BEFORE, is ON or is AFTER a certain date that gets selected from an html5 calendar (input type =date). What I'm trying to do is now add an additional option for them to select the start date/end date to be IN BETWEEN two dates. So I preferably want them to select the ' In between ' option, which should trigger a calendar (or two actually) when selected that will allow them to pick those two dates and allow me to store those two values.
I'm new to Javascript/HTML so any help would be very much appreciated!
Here is what I have so far in my HTML file:
<h6 style="float:left">Filter By Date:</h6>
<div style="float:left;clear:left;">
<label for="start">Start Date </label>
<select name="start_op" v-model="filter.start_option" #change="getVueTasks(pagination.current_page)"> <!--As soon as they select a department, call getVueTasks to filter what tasks are displayed-->
<option value="lt">Is Before</option>
<option value="eq" selected>Is On</option>
<option value="gt">Is After</option>
<option value="bt">Is Between</option>
</select>
<br/>
<input type="date" id="start" v-model="filter.start" #change="getVueTasks(pagination.current_page)">
</div>
<div style="float:left">
<label for="end">End Date </label>
<select name="end_op" v-model="filter.end_option" #change="getVueTasks(pagination.current_page)"> <!--As soon as they select a department, call getVueTasks to filter what tasks are displayed-->
<option value="lt">Is Before</option>
<option value="eq" selected>Is On</option>
<option value="gt">Is After</option>
<option value="bt">Is Between</option>
</select>
<br/>
<input type="date" id="end" v-model="filter.end" #change="getVueTasks(pagination.current_page)">
</div>
Note: I do have a separate vue/js file that handles mainly back-end stuff.
You can do something like this -
<select name="start_op" id="start_op">
<option value="lt">Is Before</option>
<option value="eq" selected>Is On</option>
<option value="gt">Is After</option>
<option value="bt">Is Between</option>
</select>
<br/>
<input type="date" id="start">
In jquery -
$(function() {
$("#start_op").on("change",function() {
var st_date= this.value;
if (st_date=="") return; // please select - possibly you want something else here
$('#start').click();
});
});
Hope this will helpful for you.

I have a series of select parts of a form, the javascript hides multiple possibilities for the following dropdown until the current drop down has a selection made, this determines which dropdown the user sees using the style="display:none;" attribute and javascript to switch it to block, .css({'display':'block'});.
The problem is that each <select> segment has the same name, e.g. <select class="form-control" name='phylum' id="sel1_1" style="display:none;"> this name='phylum' is used in the post phase of the form and needs to be associated with whichever dropdown list is used, but all of these have the default as 0 so if this is set it is overwritten by the final select in the list.
In javascript I therefore need to disable the html code, switching display:none; to display:block; has no effect as it is style only. Could I add disabled to all the <select> elements and somehow activate the required one?
Some example html and javascript snippets follow.
html
<div class='col-12 left'>
<div class='form-group'>
<label id="sel1_0" style="display:none;" for='uname'>Phylum/Division</label>
<select class="form-control" name='phylum' id="sel1_1" style="display:none;">
<option value="phylum" data-value="0">Choose</option>
<option value="Annelid" data-value="1">Annelid</option>
<option value="Arthropod" data-value="2">Arthropod</option>
<option value="Bryozoa" data-value="3">Bryozoa</option>
<option value="Chordata" data-value="4">Chordata</option>
<option value="Cnidaria" data-value="5">Cnidaria</option>
<option value="Echinoderm" data-value="6">Echinoderm</option>
<option value="Mollusc" data-value="7">Mollusc</option>
<option value="Nematode" data-value="8">Nematode</option>
<option value="Platyhelminthes" data-value="9">Platyhelminthes</option>
<option value="Rotifer" data-value="10">Rotifer</option>
<option value="Sponge" data-value="11">Sponge</option>
</select>
<select class="form-control" name='phylum' id="sel1_2" style="display:none;">
<option value="0" data-value="0">Choose</option>
<option value="1" data-value="1">C1</option>
<option value="2" data-value="2">D1</option>
</select>
</div>
</div>
javascript
$("#sel0").change(function() {
$('#sel1_1').css({'display':'block'});
The following doesn't seem to work
$('#sel1_1').css({'active'});
I'm trying to set the value of a dropdown list based on another dropdown list value inside Angular and using jQuery, it works and it auto selects the wanted value but it doesn't add the value to the database after submitting. I'm sure everything is fine concerning the database connection because choosing any other selected value (for example euro in this case) is added to database.
$(document).ready(function() {
$("#country").change(function() {
var val = $(this).val();
if (val == "usa") {
$("#currency").val("dollar");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form (ngSubmit)="onSubmit()">
<select id="country" name="country">
<option value="usa">usa</option>
<option value="france">france</option>
</select>
<select id="currency" name="currency">
<option value="dollar">dollar</option>
<option value="euro">euro</option>
</select>
<button type="submit" class="btn btn-primary">submit </button>
</form>
NB: Dollar becomes selected but when submitting it's not added to database, whereas if I remove the jQuery function and choose manually the currency , it adds to the database and everything is fine .
The jQuery code seems to be good... but my question is, why are you using jQuery to update a form in Angular.
Did you evaluate use tempalte-driven or reactive forms instead? Below you can find your form written as template driven.
<form (ngSubmit)="onSubmit()">
<select id="country" name="country" (change)="onCountryChange()" [(ngModel)]="selectedCountry">
<option
*ngFor="let country of countries"
[value]="country">
{{ country }}
</option>
</select>
<select id="currency" name="currency" [(ngModel)]="selectedCurrency">
<option
*ngFor="let currency of currencies"
[value]="currency">
{{ currency }}
</option>
</select>
<button type="submit" class="btn btn-primary">submit </button>
</form>
And in this plunkr you can find the full example using template-driven form... but if I where you, I would go for the reactive form approach.
I'm fairly new to javascript and I'm trying to make an form for my website and I'm stuck on the javascript,
This is what I have:
<script type="text/javascript">
function hide(opt) {
if (getElementsByClassName(opt).style.display='none';){
getElementsByClassName(opt).style.display='block';
}
else{
getElementsByClassName(opt).style.display='none';
}
}
</script>
What I intended the script to do was recieve a variable (the option chosen by the user) and then reveal all the elements with the class of the same name (so if the option was orc the orc div would be displayed, but be hidden if the option chosen was elf etc.)
Html:
<form name="chargen" action="" method="post">
Name:<Input name="name" type="text" />
Gender:<select name="gender">
<option>Choose Gender...</option>
<option>Male</option>
<option>Female</option>
</select>
Species:<select name="species" onchange="hide(document.chargen.species.options[
document.chargen.species.selectedIndex ].value)">
<option> Choose Species...</option>
<option value="human">Human</option>
<option value="orc">Orc</option>
<option value="elf">Elf</option>
<option value="dwarf">Dwarf</option>
<option value="drow">Drow</option>
<option value="ent">Ent</option>
</select>
<div class="human" style="display:none;">
Sub Species:<select name="subspecies1">
<option>Norseman</option>
<option>Hellenic</option>
<option>Heartlander</option>
</select>
</div>
<div class="orc" style="display:none;">
Sub Species:<select name="subspecies2">
<option>Black Orc</option>
<option>Fel Orc</option>
<option>Green Orc</option>
</select>
</div>
<div class="human" style="display:none;">
Homeland:<select name="homeland1">
<option>Choose Homeland...</option>
<option value="citadel">Citadel</option>
<option value="wildharn">Wildharn</option>
<option value="Merith">Merith</option>
</select>
</div>
<div class="orc" style="display:none;">
Homeland:<select name="homeland2">
<option>Choose Homeland...</option>
<option value="1">Berherak</option>
<option value="2">Vasberan</option>
</select>
</div>
Unfortunately nothing happens when I change the contents of the species combobox (I've tried on multiple browsers) What am I doing wrong?
I realise that getElementsByClassName() is a HTML5 function, but according to the interwebs it is compatible with all major browsers.
Thanks for your time
getElementsByClassName returns an array, you must iterate on the result. And be careful to the = in tests (instead of ==).
But I suggest you have a look at jquery. Your life will be easier as what you want can be done as :
$('.human, .orc, .elf, .dwarf, .drow, .ent').hide();
$('.'+opt).show();

I have spent about an hour or two trying to find out how to use JavaScript to create a text field when a certain value is selected from a drop down list.
Here is the code for the drop down menu if that's of any help. I'd have attempted to write the code to do this myself, but I am still very unfamiliar with how to write JavaScript code
<select name="claim">
<option value="">Select a Claim</option>
<option value="Insurance">Insurance</option> // this option I want when selected to create a text field
<option value="Warranty">Warranty</option>
</select>
try this hope it helps
<div id="area">
<select id="claim" name="claim">
<option value="">Select a Claim</option>
<option value="Insurance">Insurance</option>
<option value="Warranty">Warranty</option>
</select>
</div>
and script
$(document).ready(function(){
$("#claim").change(function(){
$("#area").find(".field").remove();
//or
$('#area').remove('.field');
if( $(this).val()=="Insurance")
{
$("#area").append("<input class='field' type='text' />");
}
});
});

I have two select boxes (one for Car Types and the other for Car Models) in a web page that I would like to change one of them according to the other using JavaScript.
The code sample is as in the following:
<html>
<head>
<script type="text/javascript">
function showCarModels(CarTypeVaraiable)
{
//I want to hide all the options in the CarModelsList and select the options with name property value equals to CarTypeVaraiable Value .. How I can write this in JavaScript ?????
}
</script>
</head>
</script>
<body>
<p>Selecting Car Models depending on the Car Type Value ..... </p>
Car Type<select id="selCarType" name="selCarType" class="selCarType" size="1" onchange="showCarModels('selCarType');">
<option class="City" value="0" selected="selected">choose Car Type</option>
<option class="CarType" value="100" >Toyota</option>
<option class="CarType" value="200" >Chevrlolet</option>
<option class="CarType" value="300" >Kia</option>
</select>
Car Model
<select id="selCarModel" name="selCarModel" class="selCarModel" size="1">
<option class="City" value="0">choose Car Model</option>
<option class="CarType" value="110" name="100" title="13" >Toyota optra</option>
<option class="CarType" value="120" name="100" title="13" >Toyota Aveo</option>
<option class="CarType" value="130" name="100" title="13" >Toyota Corolla</option>
<option class="CarType" value="210" name="200" title="13" >Chevrlolet Optra</option>
<option class="CarType" value="220" name="200" title="13" >Chevrlolet Aveo</option>
<option class="CarType" value="301" name="300" title="13" >Kia Rio</option>
<option class="CarType" value="450" name="300" title="13" >Kia Optima</option>
<option class="CarType" value="600" name="300" title="13" >Kia Serato</option>
</select>
</body>
</html>
What I should write in the code to carry out this dependency between the two dropdown lists?
You can do it in HTML + javascript + CSS, however once your structure grows it will be very hard to maintain. It is also easy to make typo and it is hard to test.
Better solution would be to use AJAX - store values for all categories in the database and create new select with options returned by server. You will have generic solution and adding new category + values is just adding records to the database, no need of changing html + js + css.
UPDATE:
I am not sure what backend language do you use, if it is php then you can take a look here: w3schools ajax example. If you use something else, then idea remains the same. Here you have beginning of ajax tutorial by w3schools. The example displays personal information after choosing a name from select, but you can just wrap the output in select tag and generate option for each out.
