I'm new in this domain so please excuse me if I don't speak technically correct.
I have a form with a red border. When I enter a character in the form, the red border has to disappear. How can I do this in JavaScript?
Thank you very much!
$(function(){
$('form').submit(function(){
event.preventDefault();
});
$('input').on('keyup',function(){
if($(this).val() === ""){
$(this).addClass('error');
} else {
$(this).removeClass('error');
}
});
});
.error {
border-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<form>
<label> Your Name:
<input type="text" placeholder="enter name"/>
</label>
<button type="submit">Submit</button>
</form>

This code are working fine, but when I write on "#sub_id" field then remove all existing value on "#landing" field but I can not remove, I need to add "#sub_id" after "#landing" value.
<html>
<body>
<form>
<label for="p_url">landing page</label>
<input type="text" id="landing" name="p_url" placeholder="Campaign Name" value="www.example.com?" readonly>
<label for="pi">Promotional Info</label>
<input type="text" id="sub_id" name="pi" placeholder="sub_id">
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#sub_id").keyup(function(){
$("#landing").val($("#sub_id").val());
});

Try with:
$("#landing").val($("#landing").val() + $("#sub_id").val());

Is there some way to make autocompleting by the first letter for select dropdown list not on jQuery but on PURE JavaScript? Something like [only example !!!]:
<input type="text" onkeyup="autoComplete();" />
<select id="mySelectDropdwonList">
<option>John</option>
<option>Michael</option>
<option>Toml</option>
</select>
<script type="text/javascript">
function autoComplete() {
// what is the code ??
}
</script>
It should work like the jQuery-solution by the link http://harvesthq.github.io/chosen/ but on pure JS
A solution just in HTML5:
<input type="text" list="mySelectDropdwonList" />
<datalist id="mySelectDropdwonList">
<option>John</option>
<option>Michael</option>
<option>Toml</option>
</datalist>

I have created a filter button. When clicking it the filter button should be highlighted via shadow. Can please anybody give some suggetions?
Here you go:
.myfilter:focus {
box-shadow: 0 0 0 4px #FFFF00; /* use any color you like*/
}
<input class="myfilter" type="text" placeholder="click me" value="">
<input class="myfilter" type="button" value="Click me too">
I used CSS focus to highlight the input when it is clicked

I want to call the function in every input pass on textbox, but it does not work., either when i enter any input or remove input..it is work like intellisense textbox
<input id="btnSearch" type="text" value="Search" class="search_btn" onchange="Call()" />
<script>
function Call()
{
alert("Me");
}
</script>
Probably what you want to do is -
<input id="txt_Search" type="text" onchange="Call()" />
<script>
function Call()
{
alert("Search suggestions can come here!!");
}
</script>
Or, using simple jQuery
$("#txt_Search").keyup( function() {
var searchQuery = $("#txt_Search").val();
alert("Seacrh suggestion satrting with - " + searchQuery);
});
you can also use textbox events -
<input id="txt1" type="text" onchange="SetDefault($(this).val());" onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();">
jquery -
function SetDefault(Text){
alert(Text);
}
Try This
