I'm using Element.scrollIntoView(). The scrolling is working, but it breaks the layout of my whole page at the same time. Following is the demo:
* {
margin: 0;
padding: 0;
}
html, body {
width: 100%;
height: 100%;
}
.content {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
overflow: hidden;
background-color: lightgray;
}
ul {
position: absolute;
width: 100%;
height: 300px;
left: 0;
bottom: 0;
background-color: gray;
overflow-y: scroll;
}
li {
list-style: none;
}
#div {
position: absolute;
width: 100%;
height: 300px;
left: 0;
bottom: -300px;
background-color: darkgray;
}
button {
position: absolute;
right: 0;
bottom: 0;
}
<div class=content>
<!-- it's the ul to scroll, staying at the bottom of the page -->
<ul>
<li id=li>abc</li>
<li>def</li>
</ul>
<!-- it's the div hidden under the bottom edge of the page -->
<div id=div>i should stay hidden.</div>
<button onclick=li.scrollIntoView();>scrollIntoView</button>
</div>
I hide a <div> under the bottom edge of the page. When I scrollIntoView the 1st <li> in <ul>, the hidden <div> is pulled out. Not only the <div>, the whole content of the page is pulled up for 300px.
I expect it to simply scroll the <li> into view of <ul>. Why is it affecting the layout of the whole page?
I think I find the answer myself. See this answer. It's about anchors, but scrollIntoView share the same mechanism internally I think.
The browser will try best to ensure the element is visible. When it's in a container, it will first scroll the container to a position with best visibility, so the contents are pulled up.
Using $xpath = new DOMXpath($doc) by no means I could not get div (and its children) if it is placed under anchor.
In XPath:
html[1]/body[1]/div[3]/div[1]/div[1]/div[1]/div[1]/div[1]/div[1]/div[1]/div[1]/div[1]/a[1]/div[1]/div[2]/div[1]/div[2]/img[1]
I evaluated elements one by one starting from body and when I reached the anchor it was the last tag in XPath that could be read.
I know this is not the best practice to place block elements into anchors but this html page is not mine and I cannot modify it.
Please advise if there is any trick to get it?

I will answer to myself :)
I took xpath from google chrome, but I did not take into account that what you see in browser is not necessary to be the same with html source as the browser shows content after javascript processing.

I'm trying to make a responsive jssor slider with thumbnails, but the thumbnails always should have the same height. I've set the ThumbnailNavigatorOptions.$Scale to false and put the thumbnail navigator into a wrapper (as suggested here), but it doesn't work. The thumbnail navigator is scaling. If I remove the wrapper, it doesn't scale, but the layout is screwed up. Also the thumbnails should be always centered horizontally.
Here what I've tried (if you put that html into the demos-jquery folder of jssor, it will load):

For anyone with a similar issue, I've ended up switching to LightGallery, which is a better implementation for displaying images in that way. Jssor is awesome for banners, but I found the other one for a gallery purpose better.
I have my jssor slider set up to display 3 slides at a time similar to this example. It works great, but let's say I have 4 slides. I want the first page of slides to have the first three slides and the second page to only contain the 4th slide as such (1 2 3) (4 ). Instead, the second page loops and includes the initial 2 slides (1 2 3) (4 1 2).
Is there a way to prevent the first two slides from being included in the second page? My initial thought is to create blank dummy slides that fill up space that would otherwise be occupied by the first 2 slides, but I was hoping there was a line in the javascript I was missing. Any ideas?
You can combine your 4 slides to 2 slides. (1 2 3) -> (1) and (4) -> (2)
See following example code,
<div u="slides" style="cursor: move; position: absolute; left: 0px; top: 0px; width: 606px; height: 150px; overflow: hidden;">
<div>
<img src="1.png" style="position: absolute; top: 0px; left: 0px; width: 200px; height: 150px; />
<img src="2.png" style="position: absolute; top: 0px; left: 203px; width: 200px; height: 150px; />
<img src="3.png" style="position: absolute; top: 0px; left: 406px; width: 200px; height: 150px; />
</div>
<div>
<img src="4.png" style="position: absolute; top: 0px; left: 0px; width: 200px; height: 150px; />
</div>
</div>
I ran the MapQuest sample code:
MQA.EventUtil.observe(window, 'load', function() {
/*Create an object for options*/
var options={
elt:document.getElementById('map'), /*ID of element on the page where you want the map added*/
zoom:10, /*initial zoom level of the map*/
latLng:{lat:39.743943, lng:-105.020089}, /*center of map in latitude/longitude */
mtype:'map', /*map type (map)*/
bestFitMargin:0, /*margin offset from the map viewport when applying a bestfit on shapes*/
zoomOnDoubleClick:true /*zoom in when double-clicking on map*/
};
/*Construct an instance of MQA.TileMap with the options object*/
window.map = new MQA.TileMap(options);
});
and generated a map ok. But looking at the HTML generated, it's not clear what the source of the map data is. I was expecting maybe an iFrame, or an image but I don't see either:
<div id="map" style="width: 800px; height: 300px; position: relative;">
<div style="width: 800px; height: 300px; z-index: 0; overflow: hidden; background: none repeat scroll 0% 0% rgb(255, 255, 255); position: relative; top: 0px; left: 0px; cursor: -moz-grab;">

How does that HTML represent a detailed map of Colorado?
Thanks
The map that you see generated by the JavaScript API is created by a set of map image tiles that are downloaded and assembled to create the map. Additional tiles are downloaded as the user pans and zooms in/out.
The map tiles are cached and hosted from various servers located around the world.
