Summary: I've created a search bar with three inputs: name, date of birth, and social security number. The functionality is all there, but I am attempting to elevate the design and am running into an issue on input focus.
When the user selects the inputs, there are focus effects in my CSS. What I am trying to do is toggle the images on input focus. Currently they are written like this:
<div class="adv-searchbar__wrapper__search-box">
<span class="column-1"><img src="/img/person-name.png" class="input-ico"/><input type="text" class="input" id="adv-input-1" placeholder="John Adam Smith"></span>
<span class="column-2"><input type="date" class="input" id="adv-input-2" placeholder="MM / DD / YY"></span>
<span class="column-3"><img src="/img/person-ssn.png" class="input-ico"/><input type="text" class="input" id="adv-input-3" placeholder="### - ## - ####"></span>
<button type="submit" class="advSearchBtn"><img src="/img/search_white.png"/></button>
</div>
The user can either click the button to execute the next function, or use the Enter key.
Effort: I've tried using if-else statements in jQuery when the user Clicks an input. The issue with that that I've found is that I am not sure how to 'measure' when the user leaves the input. So while the image will change correctly, it will not change back once the user moves on.
$('.input').click(function() {
let currIco = $(this)[0].previousSibling.src.slice(0, -4);
if ($(this).is(':focus')) {
console.log('input is focused');
currIco = currIco + '__focus.png';
$(this)[0].previousSibling.src = currIco;
} else {
console.log('input is blurred');
}
});
I've found several tutorials for changing images on click or on hover, but I haven't been able to implement those solutions to my needs.
You say in a comment that the only reason you didn't use CSS is because the images are not in the input.
As CSS is still an option for you and it is much easier to achieve in CSS (plus you haven't got a JS answer yet), take a look at the solution below.
FYI CSS-only is also a more efficient option - the more client-side processing you add, the slower the page load and the worse for SEO and user experience.
.column-1 input, .column-3 input {
background-repeat: no-repeat;
background-position: top left;
padding-left: 40px;
}
.column-1 input {
background-image: url(https://lorempixel.com/output/abstract-q-c-30-30-1.jpg);
}
.column-1 input:focus {
background-image: url(https://lorempixel.com/output/abstract-q-c-30-30-2.jpg);
}
.column-3 input {
background-image: url(https://lorempixel.com/output/abstract-q-c-30-30-3.jpg);
}
.column-3 input:focus {
background-image: url(https://lorempixel.com/output/abstract-q-c-30-30-4.jpg);
}
<div class="adv-searchbar__wrapper__search-box">
<span class="column-1">
<input type="text" class="input" id="adv-input-1" placeholder="John Adam Smith">
</span>
<span class="column-2"><input type="date" class="input" id="adv-input-2" placeholder="MM / DD / YY"></span>
<span class="column-3"><input type="text" class="input" id="adv-input-3" placeholder="### - ## - ####"></span>
<button type="submit" class="advSearchBtn"><img src="/img/search_white.png"/></button>
</div>
Obviously I haven't applied your styling to the inputs because you hadn't included it, but you can apply that the same way excluding the image.
You could, alternatively to the existing answer (provided by FluffyKitten), create a <label> element and place it after the <input>.
I too, don't recommend using JavaScript over CSS if you are indeed able to get it done in CSS.
In this case, you can separate the icon (and therefore the styling) from the rest of the input field if you so desire.
.adv-searchbar__wrapper__search-box span {
position: relative;
}
.input {
box-sizing: border-box;
padding: 2px 2px 2px 20px;
max-height: 20px;
border: 1px solid #888;
}
.input~.icon {
position: absolute;
left: 2px;
top: 0px;
height: 16px;
width: 16px;
background-image: url('https://via.placeholder.com/16?text=icon');
background-repeat: no-repeat;
}
.input:focus~.icon {
filter: blur(1px);
background-image: url('https://via.placeholder.com/16/FF9900');
}
<div class="adv-searchbar__wrapper__search-box">
<span class="column-1">
<input type="text" class="input" id="adv-input-1" placeholder="John Adam Smith">
<label class="icon" for="adv-input-1"></label>
</span>
<span class="column-2">
<input type="date" class="input" id="adv-input-2" placeholder="MM / DD / YY">
</span>
<span class="column-3">
<input type="text" class="input" id="adv-input-3" placeholder="### - ## - ####">
<label class="icon" for="adv-input-3"></label>
</span>
<button type="submit" class="advSearchBtn">
<img src="https://via.placeholder.com/16?text= "/>
</button>
</div>
Here is an other way, using focus on parent element.
span:focus-within .input-ico-focus {
display: inline-block;
}
span:focus-within .input-ico {
display: none
}
span .input-ico-focus {
display: none
}
span .input-ico {
display: inline-block;
}
.input-ico, .input-ico-focus {
width: 16px;
}
<div>
<span class="column-1">
<img src="https://i.stack.imgur.com/pd8J3.png" class="input-ico">
<img src="https://i.stack.imgur.com/XdkNO.png" class="input-ico-focus">
<input type="text" class="input" id="adv-input-1" placeholder="John Adam Smith">
</span>
</div>
I was wondering how to edit the css of a bootstrap 4 button to display the text in various different positions for a project I have in school.
Here is an image of the button
I'd like it to be where Puppies and Cost are in the same spot but x27 is enlarged to the size of the button and aligned to the right side of the button.
Does anyone know of how one could do this?
This is the current code I have that is related to this question
document.getElementById("BP").innerHTML = " Puppies x" + puppyarray.length + "<br>" + "Cost: " + puppiescost;
.dogbut:first-line {
font-size: 20px;
}
.dogbut {
font-size: 14px;
text-align: left;
}
<button id="BP" onclick="BP()" type="button" class="btn btn-light w-100 dogbut" data-toggle="tooltip" data-placement="bottom" data-original-title="Cost: 10 | +.3 BPS">
Puppies
<br>
Cost: 10 Borks
</button>
Thank you so much for your help!
There are a lot of ways you could accomplish this task. I've demo'd an example below assuming you know the height and width of this button. There are likely more clever alternatives that are more dynamic.
Basically, use flex to control the position of the elements and wrap your data values in spans to give yourself control via CSS. Using pseudo classes is a real pain for stuff like this imho.
button.my-btn{
width: 400px;
display: flex;
flex-direction: row;
justify-content: space-between;
height:80px;
}
.my-left{
display: flex;
flex-direction:column;
align-items: flex-start;
}
.number{
font-size: 40px;
line-height: 40px;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<button class="my-btn btn btn-primary">
<div class="my-left">
<span class="puppies">Puppies</span>
<span class="cost">Cost: 1331</span>
</div>
<div class="my-right">
<span class="number">x27</span>
</div>
</button>
EDIT: It would probably be important to include the JS eh
Here's how I would modify your js that modifies your DOM
document.getElementById("BP").innerHTML = `<div class="my-left">
<span class="puppies">Puppies</span>
<span class="cost">Cost: ${puppiescost}</span>
</div>
<div class="my-right">
<span class="number">x${puppyarray.length}</span>
</div>`
Assuming your button is like this.
<button id="BP"><button>
You should maybe do something this way (not tested).
var BP = document.getElementById("BP");
var span = BP.appendChild(document.createElement("span"));
span.textContent = "Puppies x" + puppyarray.length;
var small = BP.appendChild(document.createElement("small"));
small.textContent = "Cost : " + puppiescost;
Then your CSS.
#BP span {
display : block;
font-size : 13px;
}
#BP small {
font-size: 9px;
}
I'm a beginner in Python and AJAX, why when I run my app.py with app.html, the result that I want to display are replaced with a whole form?
Here is my code:
from flask import Flask, render_template, request
app = Flask(__name__,
template_folder='C:\\Users\\iyzadsyammil\\PycharmProjects\\PVT - Copy')
#app.route('/App',methods=['GET', 'POST'])
def showapp():
error = " "
finalpb= 0
x=0
logpb=0
if request.method == 'POST':
ingor = request.form['inGOR']
ingor = float(ingor)
try:
finalpb = ingor
except ValueError:
error = "Please enter an appropriate value!"
return render_template('app.html',error=error,finalpb=finalpb)
if __name__ == "__main__":
app.run(debug=True)
This is my Python Flask file

This is my html
Please have a look at my ajax part only
Updated response:
Let me rephrase my original answer: Don't use AJAX. it is completely unnecessary. Delete all of your script items. I just took your code and made it work on my local flask environment nicely without any AJAX. Here is what you need to do:
1) Update your 'buttons' so that they are inputs, type=submit and give them the value of the name of the button you desire (e.g. Calculate).
2) Your form inputs do not have a 'name' attribute. Without that, the form has no key/value association. For example, look at your inOG input. You need to give it a name...something like name="inOG".
3) I don't know why you have your C drive as a configuration item. Maybe it's a Windows thing?
Now when you debug, you should see the form values come in nicely.
You are running into problems for a few reasons:
1) Your form is far too busy. Ideally, in my experience, the form should really only contain the necessary inputs and labels. Also, it is generally not wise to format an html page using tables. You might consider using Flask-WTF if you don't feel like coding out a form in it's entirety. One of the nice things of Flask is the ability to use templates like WTF.
2) If you set up the form nicely, then you won't even need to use AJAX, which might be preferable in your case. The once the form is submitted, your Flask code should do the rest.
2) If you are bent on using AJAX it's worth noting that your AJAX post is right in the middle of your form code. Since your browser reads code sequentially, it is picking up an AJAX post before the form has finished rendering. You should insert your <script> tag either at the top of the body or at the bottom of it.
3) You are using JQuery, which means you need to wrap any executable code in a $(document).ready function. So, once you have moved your script as mentioned above, you should write is as follows:
<script>
$(document).ready(function(){
$('#fm').on('submit',function (e) {
$.ajax({
type: 'post',
url: '/App',
data: $('#fm').serialize(),
success: function (q) {
document.getElementById("pb").innerHTML= q;
}
});
e.preventDefault();
});
}
In summary, I would suggest cleaning up your form and doing away with AJAX altogether. Looking at your form data, it doesn't seem like there is anything special that would require a break away from normal form submission.
Good Luck!
So after dealing with my own issues in Flask and AJAX, I wouldn't say don't use AJAX. As an example, I had a form that needed to be submitted and it took long enough to generate a 504. Sometimes AJAX is necessary.
In the off-case where it is necessary and you happen to be using Flask (and/or FLASK-WTF) you first need to update your form element to use the new event. This can be done with the following addition.
{{ form.my_element(**{"onchange":"my_ajax_function()"}) }}
The dictionary is passed back as a kwarg to Flask forms and sets the onchange event to use my_ajax_function() (just replace this with "onclick" if it's a button)
Next update your javascript with the new function. This function should do the following:
Get any fields required to perform this work
Start the ajax request and include the url (route), the data to be sent (if any), and what action to perform on a successful/failed request.
This will update any fields as required and keep data in existing fields. I will say that it is much easier on life if you avoid AJAX and let Flask do it's thing, but sometimes this is unavoidable.
I haven't tried just returning without a response instead of using render_template, redirect, or make_response from a post request to see if the fields remain as they were, but it's definitely something to experiment with.
I've only used AJAX for creating dynamic SelectFields, but there are some promising articles on form submissions, just looks like FlaskForms doesn't know how to convert this type of request back to the Form object since they are sent as query parameters, so you'll need to manually validate the fields after they have returned. How to submit a Flask-WTF form with Ajax
I have a series of inline elements (with input text boxes) that should fit within one row. See picture below.
The number of input boxes can vary (dynamically loaded via AJAX), as can the labels of the input boxes. In the example below, it is length x width x height.
The div that the inline elements are in is a dynamic width, which depends on the content above and below this row.
In the event of the screenshot below, how can I get the input boxes to equally increase in width so that the content is justified on both sides? Is there a pure CSS solution?
.dynamicWidth {
background-color: green;
height: 400px;
position: absolute;
}
<div class="dynamicWidth">
<div>
<select>
<option>This could be longer or shorter dependending on what is dynamically loaded</option>
</select>
</div>
<hr>
<div>
<span>Length</span>
<input type="text" placeholder="length"><span> x Width</span>
<input type="text" placeholder="width"><span> x Height</span>
<input type="text" placeholder="height">
</div>
</div>
You can accomplish this using flexbox's justify-content and assigning the value of space-around to the div containing the input elements.
.dynamicWidth {
background-color: green;
width: 100%;
height: 400px;
position: absolute;
}
.dynamicWidth div:nth-of-type(2) {
display: flex;
justify-content: space-around;
}
<div class="dynamicWidth">
<div>
<select>
<option>This could be longer or shorter dependending on what is dynamically loaded</option>
</select>
</div>

If you're trying to support legacy browsers that don't support flexbox your alternative option would be to wrap each label and input in their own respective divs, give the enclosing parent of those divs a display of table and give the input divs a display of table-cell with width percentages of 33.3% (1/3s).
.dynamicWidth {
background-color: green;
width: 100%;
height: 400px;
position: absolute;
}
.dynamicWidth div:nth-of-type(2) {
display: table;
width: 100%;
}
.input-container {
width: 33.3%;
display: table-cell;
}
<div class="dynamicWidth">
<div>
<select>
<option>This could be longer or shorter dependending on what is dynamically loaded</option>
</select>
</div>

I'm building a simple image gallery with jquery but running into an annoying problem. Since the images are of various sizes I have centered them all to make it look even. However the built in fadeIn/fadeOut methods throw this centering awry and I'm not completely sure what is going on. I tried manually adding the centering class again then manually adding css but cannot get the image to center once it has been turned visible. Thoughts?
css -
.center { margin: 0 auto; }
img.invisible { display: none; }
img.visible { margin: 0 auto; display: block;}
markup -
<div id="content" class="center gallery">
<img src="images/event/event_1.jpg" alt="alt-text" class="visible" />
<img src="images/event/event_2.jpg" alt="alt-text" class="invisible" />
<img src="images/event/event_3.jpg" alt="alt-text" class="invisible" />
<div id="selection" class="overlay">
<div class="select first">
<img src="images/event/event_1_small.jpg" />
</div>
<div class="select">
<img src="images/event/event_2_small.jpg" />
</div>
<div class="select">
<img src="images/event/event_3_small.jpg" />
</div>
</div>
jQuery -
function updateImage(img_num) {
var cur_img = $("#content img.visible");
var next_img = $('#content img[src^="' + img_path + img_num + '.jpg"]');
cur_img.fadeOut('600',function() {
next_img.fadeIn('600');
next_img.removeClass("invisible").addClass("visible");
cur_img.removeClass("visible").addClass("invisible");
});
}
You are adding margin: 0 auto; only to the .visible class, you need to apply that to all of your images:
.gallery img{margin:0 auto;display:none}
.gallery img.visible{display:block}
Okay well that was surprising. To fix this problem I tried using fadeTo which revealed that the problem was the images once being made visible were given display: inline; so all it took to fix this problem was.
.gallery { text-align: center; }
I thought jQuery was just changing the opacity but it appears to also change the display. Tricky.
