I have an html select
element with an id
of background
designed to set a background image for the <div class=”results-area”>
. Then I have a print button to print the .results-area
content.
The problem is that when I wanna print the .results-area
I need to set what background image to set when printing, if I use CSS @media print
I cannot set rules which background it should print (based on user selection).
Is there another way to accomplish that?
HTML
<select id="background">
<option value="url(picture1.jpg)">picture1</option>
<option value="url(picture2.jpg)">picture2</option>
<option value="url(picture3.jpg)">picture3</option>
<option value="url(picture4.jpg)">picture4</option>
<option value="url(picture5.jpg)">picture5</option>
<option value="url(picture6.jpg)">picture6</option>
</select>
<div class=”results-area”>
...
</div>
<a id="printMe" class="btn btn-warning">Print</a>
jQuery
$('#background').change(function () {
$('.results-area').css("background-image", $(this).val());
})
$('#printMe').click(function () {
print()
});
CSS:
@media print {
.results-area{
background-image: ??????;
}
}
Add a <style>
tag to your <head>
and give it an id:
<head>
...
<style id="bg-for-print"></style>
...
</head>
Then when you want to change the background image, select that style tag and set the appropriate background image:
$("#bg-for-print").text(
"@media print {" +
".results-area{" +
"background-image: url(" + backgroundUrl + ");" +
"}" +
"}"
);
The way I solved it is as follows.
HTML
I changed the values to digits "1-2-3..." And added a class to each picture "abc..."
<select id="background">
<option class="a" value="1">Picture 1</option>
<option class="b" value="2">Picture 2</option>
<option class="c" value="3">Picture 3</option>
<option class="d" value="4">Picture 4</option>
<option class="e" value="5">Picture 5</option>
<option class="f" value="6">Picture 6</option>
</select>
<div class=”results-area”>
...
</div>
<a id="printMe" class="btn btn-warning">Print</a>
CSS
With the @media print
I specified for each class his own background-image
@media print {
.a {
background-image: url(image1.jpg) !important;
}
.b {
background-image: url(image2.jpg) !important;
}
.c{
background-image: url(image3.jpg) !important;
}
.d{
background-image: url(image4.jpg) !important;
}
.e {
background-image: url(image5.jpg) !important;
}
.f {
background-image: url(image6.jpg) !important;
}
}
JQuery
$('#background').change(function () {
if ($(this).val() === "1") {
$('.results-area').css("background-image", "url(image1.jpg)");
replace();
$('.results-area').addClass("a");
}
else if ($(this).val() === "2") {
$('.results-area').css("background-image", "url(image2.jpg)");
replace();
$('.results-area').addClass("b");
}
else if ($(this).val() === "3") {
$('.results-area').css("background-image", "url(image3.jpg)");
replace();
$('.results-area').addClass("c");
}
else if ($(this).val() === "4") {
$('.results-area').css("background-image", "url(image4.jpg)");
replace();
$('.results-area').addClass("d");
}
else if ($(this).val() === "5") {
$('.results-area').css("background-image", "url(image5.jpg)");
replace();
$('.results-area').addClass("e");
}
else if ($(this).val() === "6") {
$('.results-area').css("background-image", "url(image6.jpg)");
replace();
$('.results-area').addClass("f");
}
else {
replace();
}
});
function replace() {
$('.results-area').removeClass("a b c d e f");
};
$('#printMe').click(function () {
print()
});
It feels like a crazy way of doing it, but it did the job.
I hope this works for you too!
Set background image using jquery and set the background-size:0;
in default and background-size: inherit;
in print media
$('select').on('change', function() { $('.results-area').css("background-image",'url(\\''+this.value+'\\')'); }); $('#printMe').click(function () { window.print(); }); $('.results-area').css("background-image",'url(\\''+$('select')[0].value+'\\')');
.results-area{ width:225px; height:225px; background-size: 0; border:solid 1px red; } @media print { .results-area{ background-size: inherit; } }
