I have implemented the Spring-MVC structure in my project, where I have configured static resource handling successfully. This allows me to access CSS, JS, and images within my JSP pages without any issues.
However, I am currently facing a problem while trying to set a background image for dynamically created items using an external JS file that is linked to the JSP. The issue arises because when attempting to set the backgroundImage property as shown below (which works fine locally), it is restricted on the server due to being a static resource.
( function( $ ){
$.fn.speedometer = function( options ){
var $this = $( this );
if ( $this.length > 1 ) {
$this.each( function(){
$( this ).speedometer( options );
});
return $this;
}
var def = {
/* If not specified, look in selector's innerHTML before defaulting to zero. */
percentage : $.trim( $this.html() ) || 0,
scale: 100,
limit: true,
minimum: 0,
maximum: 100,
suffix: ' %',
animate:true,
thisCss: {
position: 'relative', /* Very important to align needle with gauge. */
width: '210px',
height: '180px',
padding: '0px',
border: '0px',
fontFamily: 'Arial',
fontWeight: '900',
backgroundImage : "url('./background.jpg')"

Attempting to address this similar to how it's done in JSP using taglib, I tried setting the backgroundImage as follows:
backgroundImage : "url(<spring:url value='/images/background.jpg'/>)"
Unfortunately, this approach did not work for me. I have also explored setting the backgroundImage through a CSS class:
.myClass{
background-image: url(<spring:url value='/images/background.jpg'/>);
}
However, calling a function to apply this has proven to be quite challenging for me. Below is the complete JS code snippet:
( function( $ ){
$.fn.speedometer = function( options ){
/* A tad bit speedier, plus avoids possible confusion with other $(this) references. */
var $this = $( this );
/* handle multiple selectors */
if ( $this.length > 1 ) {
$this.each( function(){
$( this ).speedometer( options );
});
return $this;
}
var def = {
/* If not specified, look in selector's innerHTML before defaulting to zero. */
percentage : $.trim( $this.html() ) || 0,
scale: 100,
limit: true,
minimum: 0,
maximum: 100,
suffix: ' %',
animate:true,
thisCss: {
position: 'relative', /* Very important to align needle with gauge. */
width: '210px',
height: '180px',
padding: '0px',
border: '0px',
fontFamily: 'Arial',
fontWeight: '900',
backgroundImage : "url('./background.jpg')"
},
digitalCss: {
backgroundColor:'black',
borderColor:'#555555 #999999 #999999 #555555',
borderStyle:'solid',
borderWidth:'2px',
color:'white',
fontSize:'14px',
height:'20px',
left:'72px',
padding:'0px',
position:'absolute',
textAlign:'center',
top:'65px',
width:'60px',
zIndex:'10',
lineHeight:'20px',
overflow:'hidden'
}
}
...
If you have any suggestions or recommendations for a better approach to handling this scenario, I would greatly appreciate it.
