I try to add highlighted color on the items which i move
I add css code

listItems.className = 'highlight';
var itemHeight = false;
for (var no = 0; no < listItems.length; no++) {
listItems[no].onmousedown = initDrag;
listItems[no].onselectstart = cancelEvent;
if (!itemHeight) itemHeight = listItems[no].offsetHeight;
if (MSIE && navigatorVersion / 1 < 6) {
listItems[no].style.cursor = 'hand';
}
}

The code below is for listing blogger posts within a Label Name, if the post has the specific Label Name it will be shown in this list. I would like to be able to change the appearance of how everything is displayed by changing where the post image would look, and where the title would look, change background color, add borders, shadows change the font etc ...(I know how to change the appearance with css, but I do not know how to integrate the code below with css and html) At the moment the code shows the title and the right of the title the image.

This creates stuff you can style with CSS. For example:
#postList12 li {
border: 1px solid blue;
}
Use the inspector in your browser to see what it makes. If you want to change the order of elements or add new ones you’ll have to edit the script to do that.
I can only append 1 card element from the following Javascript. Please Help.
var gb = document.getElementById('game-board');
var cardCount = document.getElementsByClassName('card');
var children = document.createElement('div');
var createCards = function() {
for (var i = 0; i < 5; i++) {
children.className = 'card';
gb.appendChild(children);
};
};
createCards();
you have only 1 "children" item that you keep moving inside the loop. One way to fix it is to clone it each time before appending:
var gb = document.getElementById('game-board');
var cardCount = document.getElementsByClassName('card');
var children = document.createElement('div');
var createCards = function() {
for (var i = 0; i < 5; i++) {
children.className = 'card';
gb.appendChild(children.cloneNode(true));
};
};
createCards();
Your code is attempting to append the same div (stored at the children variable) to gb on every iteration of the loop. Try creating a new element for each iteration instead:
var gb = document.getElementById('game-board');
var createCards = function() {
for (var i = 0; i < 5; i++) {
var children = document.createElement('div');
children.className = 'card';
gb.appendChild(children);
};
};
createCards();
.card{
width: 50px;
height: 50px;
border: 1px solid gray;
}
<div id="game-board" ></div>
I'm new to cytoscape.js, I just want to make other nodes follow when dragging one node.
Appreciate your help
Write a listener, and update the other node positions appropriately in your callback:
eles.on()
node.position()
Here is how I did it. Note you have to save off the original positions at the grab event, and then update during the drag event.
function add_drag_listeners()
{
var all = cy.elements("node");
for (j = 0; j < all.length; j++)
{
cynode = all[j];
cynode.on("grab",handle_grab);
cynode.on("drag",handle_drag);
}
}
var grab_x = 0;
var grab_y = 0;
var drag_subgraph = [];
function handle_grab(evt)
{
grab_x = this.position().x ;
grab_y = this.position().y ;
var succ = this.successors();
drag_subgraph = [];
var succstr = "";
for (i = 0; i < succ.length; i++)
{
if (succ[i].isNode())
{
var old_x = succ[i].position().x;
var old_y = succ[i].position().y;
succstr += " " + succ[i].data("id");
drag_subgraph.push({old_x:old_x, old_y:old_y, obj:succ[i]});
}
}
}
function handle_drag(evt)
{
var new_x = this.position().x;
var new_y = this.position().y;
var delta_x = new_x - grab_x;
var delta_y = new_y - grab_y;
for (i = 0; i < drag_subgraph.length; i++)
{
var obj = drag_subgraph[i].obj;
var old_x = drag_subgraph[i].old_x;
var old_y = drag_subgraph[i].old_y;
var new_x = old_x + delta_x;
var new_y = old_y + delta_y;
obj.position({x:new_x, y:new_y});
}
}
I'm a begginer with javaScript. and I want to create number of windows (div) with loop operation only with javaScript.
This is my code:
var numOfWindows = 3;
var arrayDiv = new Array();
for (var i = 0; i < numOfWindows; i++)
{
arrayDiv[i] = document.createElement('div');
arrayDiv[i].id = 'block' + i;
arrayDiv[i].style.backgroundColor = 'green';
arrayDiv[i].className = 'block' + i;
document.body.appendChild(arrayDiv[i]);
}
but I see a blank screen.
Your JavaScript works perfectly, if you give the created elements some content, or specific dimensions in CSS:
var numOfWindows = 3;
var arrayDiv = new Array();
for (var i = 0; i < numOfWindows; i++)
{
arrayDiv[i] = document.createElement('div');
arrayDiv[i].id = 'block' + i;
arrayDiv[i].style.backgroundColor = 'green';
arrayDiv[i].className = 'block' + i;
// setting the textContent to the 'i' variable:
arrayDiv[i].textContent = i;
document.body.appendChild(arrayDiv[i]);
}
JS Fiddle demo.
Or:
var numOfWindows = 3;
var arrayDiv = new Array();
for (var i = 0; i < numOfWindows; i++) {
arrayDiv[i] = document.createElement('div');
arrayDiv[i].id = 'block' + i;
arrayDiv[i].style.backgroundColor = 'green';
arrayDiv[i].className = 'block' + i;
// setting the class-name of the created elements:
arrayDiv[i].className = 'bordered';
document.body.appendChild(arrayDiv[i]);
}
JS Fiddle demo.
Give your div a specified width and height.
div.style.width = '10px';
div.style.heigt = '10px';
Or give it content.
