I found a weird problem in my project. I'm using Spring MVC, Tiles, JSPX and Boostrap.
I have a navbar in my header page, then I added a span to show a badge like https://getbootstrap.com/docs/3.3/components/#badges.
Till here nothing strange. But If I add an id on span tag and there is an error inside the html code, I can't see any log or exception.
Here the code
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
<span class="fa fa-male"><jsp:text/></span>
<span class="badge badgeNavbar" id="badgesContrattiDaApprovare">
<jsp:text/>
</span> ${clienti}
<span class="caret"><jsp:text/></span>
</a>
<ul class="dropdown-menu">
...
</ul>
Instead If I remove id="badgesContrattiDaApprovare" I can see the exceptions.
Are there any conflicts between span and id?
SO: Why if I add the id attribute to the span inside bootstrap navbar the JSP/Tiles exceptions aren't shown inside the rendered view?
For example here if an exception occurs without the id attribute:
Instead, if I add the id attribute is like the rendering is stopped, and I see only a blank page. The generated/rendered html code is incomplete.

As already asked here, i need to add dropdown into the table element which has scroll to x-direction (horizontal scroll) and in the last column there is one three dot icon where I need to add dropdown element. But dropdown menu always clips inside the table which is not good user experience.
As per the, Bootstrap doc, there is option named boundary but I am not getting how this boundary option works or even don;t know whether it entirely works or not and how.
If i remove relative position from dropdown parent which is with class dropdown and also remove from all the ancestors which is not static then I am getting correct behavior. I don;t feel it's the correct way to remove position relative only for getting this dropdown-menu out of container.
Is this the only solution or the boundary makes sense? I am not getting how popperconfig works and how should I use boundary aka data-bs-boundary?
In earlier version of bootstrap, with some code tweak, I used to get entire dropdown all the way at the end of the body element but not sure with this.
So here there are multiple things to consider when dropdown actually clips under the overflow parent/one of the ancestor parents(grand, great-grand and so on...)
We can apply position static to all parent/s to apply as a quick fix this without any javascript extra code when there are no css transformations/opacity (or any other property which creates stacking context) applied on any of them. But this is not helpful when any third party library adds many other elements in between.
We also need to consider the case when there is transform property applied to the parent/s because transform also creates a new stacking context even for the fixed position element. So in that case we have to move the dropdown menu out of the container. This question's answer discuss more on it.
Considering that there are multiple dropdowns with id's like myPopperDropdown-1, 2 etc.. which all are clipped under overflow hidden on one of the parent/s, we can do something like this.
$("[id*='myPopperDropdown-']").each(function(el,index) {
var parent, dropdownMenu, left, top;
$(this).on('show.bs.dropdown',function(){
parent = $(this).parent();
dropdownMenu = $(this).find('.dropdown-menu');
left = dropdownMenu.offset().left - $(window).scrollLeft();
top = dropdownMenu.offset().top - $(window).scrollLeft();
$('body').append(dropdownMenu.css({
position:'fixed',
left: left,
top: top
}).detach());
})
$(this).on('hidden.bs.dropdown',function(){
$(this).append(dropdownMenu.css({
position:'absolute', left:false, top:false
}).detach());
})
})
body {margin: 10px !important}

<li><a class="dropdown-item" href="#">Another action</a></li>

As of now not found any other better solution than this and even changing in popperConfig also not working due to restrictions applied even on fixed positioning.
Original answer was at Bootstrap dropdown clipped by overflow:hidden container, how to change the container?. which is somewhat modified here.
I'm making an E-commerce website and in the products section (inside admin), I was trying to display only 10 products per page. I'm new to Spring and while writing the code, I encountered an error (given in title) when trying to add the next page button. However, the code works fine with the Previous button and all the page numbers. Here's my code for the pagnation section:
<nav class="mt-3" th:if="${count > perPage}">
<ul class="pagination">
<li class="page-item" th:if="${page > 0}">
<a th:href="#{${#httpServletRequest.requestURI}} + '?page=__${page-1}__'" class="page-link">Previous</a>
</li>
<li class="page-item" th:each="number: ${#numbers.sequence(0, pageCount-1)}" th:classappend="${page==number} ? 'active' : ''">
<a th:href="#{${#httpServletRequest.requestURI}} + '?page=__${number}__'" class="page-link" th:text="${number+1}"></a>
</li>
<li class="page-item" th:if="${page pageCount-1}">
<a th:href="#{${#httpServletRequest.requestURI}} + '?page=__${page+1}__'" class="page-link">Next</a>
</li>
</ul>
</nav>
The first 2 li's work fine and I get the list of pages and also the previous button. But on adding the Next button, I get the error mentioned above.
First of all, please always provide the actual error message. Otherwise we are just guessing.
My guess is that th:if expects a boolean expression and what you have doesn't look like boolean to me: th:if="${page pageCount-1}"
Change that to something like page == pageCount-1, but again depends on what you want to display there
I am trying to scrape a web page for NAME OF COMPANY and CITY AND STATE OF COMPANY shown below.
I have an xpath code snippet that identifies both text elements at the same time:
// span[starts-with(#class,"text-align")]/text()[2]
This xpath snippet pulls the first text value (COMPANY NAME). How do I get the second text element (CITY,STATE)?
A snip of the web page code looks like this:
<div>
<ul class="pv-top-card-v3--experience-list">
<li>
<a class="pv-top-card-v3--experience-list-item" href="#" data-control-name="position_see_more" data-ember-action="" data-ember-action-172="172">
<img src="https://media.licdn.com/dms/image/C4E0BAQFhA8h46hvabA/company-logo_100_100/0?e=1582761600&v=beta&t=VAeZqaGu3Lu6Ol_n5kiiI74FSRuSOZA1ggAI5qTVRjE" id="ember173" class="EntityPhoto-square-1 flex-shrink-zero ember-view">
<span id="ember174" class="text-align-left ml2 t-14 t-black t-bold full-width lt-line-clamp lt-line-clamp--multi-line ember-view" style="-webkit-line-clamp: 2"> THIS IS THE NAME OF A COMPANY
<!----></span>
</a>
</li>
<li>
<a class="pv-top-card-v3--experience-list-item" href="#" data-control-name="education_see_more" data-ember-action="" data-ember-action-176="176">
<img src="https://media.licdn.com/dms/image/C560BAQEr2uQX-x2EwQ/company-logo_100_100/0?e=1582761600&v=beta&t=aDbYLUDMvlS4DpwOLjOaQj3Dj60C_cYLC5UUvGoyld0" id="ember177" class="EntityPhoto-square-1 flex-shrink-zero ember-view">
<span id="ember178" class="text-align-left ml2 t-14 t-black t-bold full-width lt-line-clamp lt-line-clamp--multi-line ember-view" style="-webkit-line-clamp: 2"> THIS IS THE CITY AND STATE OF COMPANY
<!----></span>
</a>
</li>
</ul>
</div>
The xpath string is picking up the two span elements using class. I can't use the span id attributes because they are dynamic and change with each page (one page per company).
Can someone advise how I extract the desired text?
Thanks.
point to the li level.
//ul/li[2]/a/span[starts-with(#class,"text-align")]
I wanted to display navigation element as active (class nav-item active) when that element is clicked and the other elements with the non active class (nav-item). I am also using Thymeleaf layouts.
In the controller i have following code
#GetMapping("/login")
public String getLoginPage(Model model) {
model.addAttribute("activeLink", "Login");
return "login";
}
In the layout.html file (this file contains common header and footer for all pages), i have following code
<nav th:replace="navigation.html :: navibar(activeLink=${activeLink})"></nav>
In the navigation.html (this file only has navigation related code), i have code similar to
<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top" th:fragment="navibar(activeLink)">
<a class="navbar-brand" href="/title">Title</a>
<div class="collapse navbar-collapse" id="navbarsExampleDefault">
<ul class="navbar-nav mr-auto">
<li th:class="${#strings.equals(activeLink, 'Home')} ? 'nav-item active' : 'nav-item'"><a class="nav-link" href="/">Home<span class="sr-only">(current)</span></a></li>
<li th:class="${#strings.equals(activeLink, 'Register')} ? 'nav-item active' : 'nav-item'"><a class="nav-link" href="/register">Register</a></li>
<li th:class="${#strings.equals(activeLink, 'Login')} ? 'nav-item active' : 'nav-item'" sec:authorize="isAnonymous()"><a class="nav-link" th:href="#{/login}">Login <span class="sr-only">(current)</span></a></li>
<li class="nav-item active" sec:authorize="isAuthenticated()"><a class="nav-link" th:href="#{/logout}">Logout <span class="sr-only">(current)</span></a></li>
</ul>
</div>
In the template returned by the controller (login), I do not have any navigation links specific code.
The above code is working, but is there a better simpler way to active navigation items?
Also, if I use flash attributes
redirectAttributes.addFlashAttribute("activeLink", "Register");
in the controller, then the functionality doesn't work
To avoid adding the activeLink to the model you can pass the activeLink when you include the fragment.
Like:
<div th:replace="nagivation :: navibar('Login')"></div>
Btw. you can remove the .html after the layout name.
So i'm using the jQuery waypoints plugin for the navigation of a single page site
Right now it looks like this:
<div class="navigation">
<ul id="navi">
<li data-slide="1">DC3</li>
<li data-slide="2">THE ABOUT</li>
<li data-slide="3">THE WORK</li>
<li data-slide="4">THE CLIENTS</li>
<li data-slide="5">THE WHO</li>
<li data-slide="6">CONTACT</li>
</ul>
and each data-slide moves to a separate div like this:
<div class="slide" id="slide1" data-slide="1" data-stellar-background-ratio=".5">
What I want to do is use the same navigation on a second page, that will target each data-slide div on teh original page. Is there a way to do this?
A very simple solution is to used named anchors. In the HTML, next to each element you want to target add a new anchor element like <a id="slide"></a> and then you can link to that anchor's position on the page by using a fragment in your URL like so example.html#slide.
