How Can I add an Html elements inside a Cytoscape node?
E.g: I want to add to every node - 2 small buttons, so the user can click on each one of the buttons and the value inside this node will change.
Example of the graph I want to create

It's not possible to render HTML in a canvas, nor would you probably want to for performance. If you really want it on the node, I suggest creating an overlay -- though that has its own set of complications in its implementation. Otherwise, you're far better off placing interactive elements separately from a node (e.g. tooltip, sidebar, menu, etc...).
mxGraph seems to do it by using an SVG foreignObject tag, and within that HTML like so:
<g style="cursor: move;">
<g>
<foreignObject style="overflow: visible; text-align: left;" pointer-events="none" width="100%" height="100%">
<div style="display: flex; align-items: unsafe center; justify-content: unsafe center; width: 78px; height: 1px; padding-top: 1212px; margin-left: 839px;">
<div style="box-sizing: border-box; font-size: 0; text-align: center; ">
<div style="display: inline-block; font-size: 12px; font-family: Helvetica; color: #000000; line-height: 1.2; pointer-events: all; white-space: normal; word-wrap: normal; ">
<div>Some HTML inside SVG</div>
</div>
</div>
</div>
</foreignObject>
</g>
</g>
Not sure I want to go there in Cytoscape as its API is too nice to start working round and you'd need to deal with the update event flow, but mxGraph is a fantastic toolkit worth knowing about in this space.

I am trying to make a component with buttons inside a div, I am having issues, because the styles are not applying on the buttons, I guess I should not use slot here. Can someone guide me?
Component
<template>
<div :class="[$style.btnGroup]" v-bind="$attrs">
<slot :class="$style[variant]">/>
</div>
</template>
How I use this
<ButtonGroup variant="warning">
<button>Test</button>
<button>Test</button>
<button>Test</button>
</ButtonGroup>
I use css module
<style module>
.btnGroup button {
position: relative;
border: none;
font-weight: 400;
border-radius: 0.25rem;
cursor: pointer;
font-size: 1rem;
padding: 0.5rem 1rem;
transition: 0.1s;
}
.primary{
background: var(--primary-bg);
border: 1px solid var(--primary-bg);
color: white;
}
.warning {
background: var(--warning-bg);
border: 1px solid var(--warning-bg);
font-size: 1rem;
padding: 0.5rem 1rem;
transition: 0.1s;
color: black;
}
etc. for each variant I have different style.
You are applying the class on the button group not the buttons that are inside, to solve this instead of binding the class to the slot bind another variable and use that variable binding on each button or you can solve it through css thats why i suggested you show us the css give a class to the buttongroup the way you are doing and in css do as so:
<slot class="buttongroupclass">/>
.buttongroupclass button{
//the css you want to apply
}
i've just created new component with navbar code within:
<template>
<!-- Navigation -->
<nav class="navbar navbar-expand-lg navbar-dark bg-dark static-top">
.....
</template>
and my index.html without any changes.
I've tried to make changes based on my googling results, actually set my own style to nav tag didn't help.
If you are using VUE CLI then in you App.vue there will be a style block like this
<style>
#app {
font-family: 'Avenir', Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
</style>
because of this margin-top: 60px this white space is there. Vue CLI provides this default styling for their default components, you can remove it.
I hope this helps
So use this in App.vue, reasons to set the default for the web base
<style>
* {
padding: 0px;
margin: 0px;
box-sizing: border-box;
}
</style>
I have an <a> tag in html, and I want it to be ellipsis. But when I add a <div> inside the <a> tag, 'text-overflow' doesn't work.
HTML:
<div class=boxed>
<h1>text-overflow Attribute Sample</h1>
<a href="#" class="caption">
<!----><div style="width:100px;height:20px;border: 1px solid red"></div>
Each box (div element) below contains the following text:
</a>
</div>
CSS:
div.boxed {
width: 200px;
height: 200px;
border: 1px solid blue;
font: 14px Times New Roman, serif;
overflow:hidden;
'position:relative;
}
a.caption {
overflow:hidden;
white-space: nowrap;
text-overflow: ellipsis;
display:block;
text-decoration:none;
float:left;
text-align:left;
}
http://jsfiddle.net/nPzsy/
After removing the <div>, the 'text-overflow' works again.
First of all, div is a block level element and a is an inline level element, so you cannot use a div inside an anchor tag b...so you should use any other inline tag (like small , span etc)
Secondly, if you have to use a div inside div, you can wrap your text in another tag like this ....
<div class=boxed>
<h1>text-overflow Attribute Sample</h1>
<div class="caption">
<!----><div style=" width:100px;height:20px;border: 1px solid red"></div>
<span class='textTrunc'>Each box (div element) below contains the following text:</span>
</div>
and css of class textTrunc:
.textTrunc{
overflow:hidden;
white-space: nowrap;
text-overflow: ellipsis;
display:block;
}
Is there any way to get all attributes of dom element in DOJO (not specific one like domAttr.get("nodeId", "foo")).
<div style="border-width: 2px; border-color: #000000; border-radius: 0px; -moz-border-radius: 0px; height: 100px; background-color: #FFFFFF; -webkit-border-radius: 0px; position: absolute; z-index: 900; width: 193px; left: 57px; top: 106px;" position="absolute" height="100px" width="193px" background-color="#FFFFFF" border-color="#000000" border-width="2px" z-index="900" -webkit-border-radius="0px" -moz-border-radius="0px" border-radius="0px" left="57px" top="106px"></div>
I want to read all attributes in div tag.
Thanks in advance.
I'm not sure if Dojo has a wrapper for this (I've done a brief search of the 1.8.3 source), but you can use Node.attributes.
Dojo does use Node.attributes in places like here in parser.js. Note the special handling of IE8 and IE6-7, to avoid falling foul of the same traps.
I have a dashboard in which I'd like a scrolling ticker. (We'll know if the UI sucks or not once it's been running on the wall for a while.) Because this is a specific purpose dashboard, we can assume a recent WebKit in our markup and use even the latest CSS3 markup if it's implemented.
This is some exemplary markup, but we're free to change it as needed, although I'd prefer to keep it relatively semantic if possible:
<div class="ticker">
<div class="itemDiv">
<img src="x">
<div class="itemBodyDiv">
<span>Upper Box</span>
<span>Lorem ipsum dolor sit amet</span>
<span>Lower Box has longer text</span>
</div>
</div>
</div>
This is the layout I'd like to achieve:
The outer solid black line is a div. The dashed line is a div that represents an individual item in the ticker. Items will scroll right-to-left using -webkit-marquee. The main body of the ticker item is the lorem ipsum text, which needs overflow-x set to cause the marquee behavior. The main body should be text-align: middle.
The problem I'm having is in finding suitable CSS markup to describe the position of the Upper Box and Lower Box. I've tried several permutations of display: inline and inline-block that didn't work. They either ruined the marquee behavior or moved the main body over. It seems that they need to be pulled out of the normal box model, but can't be absolute since they wouldn't have the marquee behavior. It seems like there should be some sort of relative positioning that is outside of the box model flow that doesn't preserve normal flow spacing that would handle cases like this, but I'm not finding it amid the many drafts of the many revisions of CSS and certainly not among the cargo cult of Google search results.
By request, this is my current non-working CSS at the state of my last experiment:
.itemDiv {
display: inline;
vertical-align: middle;
}
.itemDiv > img {
margin: 10px 10px 10px 30px;
vertical-align: middle;
height: 48px;
width: 48px;
/* border: 1px solid red; */
}
.itemBodyDiv {
display: inline;
vertical-align: middle;
}
.itemDiv span:nth-child(1) {
font-size: small;
clear:left;
vertical-align: top;
color: green;
}
.itemDiv span:nth-child(2) {
font-size: x-large;
vertical-align: middle;
color: white;
}
.itemDiv span:nth-child(3) {
font-size: smaller;
vertical-align: bottom;
color: gray;
}
Any suggestions?
You should wrap the entire scrolling message in a a div with its position set to relative. That way, you're free to absolutely position elements inside of the message absolutely while not breaking the marquee behavior:
.message
{
position: relative;
}
.upper-box
{
position: absolute;
top: 5px;
left: 10px;
}
.lower-box
{
position: absolute;
bottom: 5px;
left: 10px;
}
