Hello i have a problem with some javascript. I have a div to layout a button who does something(in my chase it will insert number 1 in to a box) and i want to change the background of the button when clicked:
你好,我有一些 javascript 的问题。我有一个 div 来布局一个按钮,它会做某事(在我的追逐中,它会将数字 1 插入到一个框中),我想在单击时更改按钮的背景:
<div id="nr1"><INPUT TYPE="button" NAME="one" OnClick="this.style = 'background-image:URL(images/totalback.gif);'; Calc.Input.value += '1'" style="width:45px; height:30px; background-color:transparent; border-style: none; border-width: 0px 0px 0px 0px"></div>
This is the code,but it ignores my background image change. Can any one help me? Short info: i have little clue about javascript.
这是代码,但它忽略了我的背景图像更改。谁能帮我?简短信息:我对 javascript 一无所知。
Thank you anyway.
还是很感谢你。

When using javascript you do it like this:
使用 javascript 时,您可以这样做:
this.style.backgroundImage="url()";
Note that javascript changes the syntax a bit, instead of background-image you use backgroundImage.
请注意,javascript 稍微更改了语法,而不是使用 backgroundImage 的背景图像。

Why dont you just use jquery its simple like this
你为什么不直接使用 jquery,就像这样简单
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#nr1 input').on("click", function(){
$(this).css({'background' : 'red'});
});
});
</script>

I hope you can use something like this in css:
我希望你可以在 css 中使用这样的东西:
#your_btn_id{
width:200px;
height:50px;
background-image: url('../images/inactive.png');
}
When clicked change the background image:
单击时更改背景图像:
#your_btn_id:active{
background-image: url('../images/active.png');
}
Hope it will work and the thing is its very simple to use.
希望它会起作用,而且使用起来非常简单。
