嗨,我正在尝试使用 Javascript 在单击时切换 div 的背景图像
这就是我为实现这一目标所做的工作:
我的代码如下
HTML:
<div id="AccordionContainer" class="AccordionContainer">
<div onclick="runAccordion(1);">
<div class="AccordionTitle" id="Accordion1Title" onselectstart="return false;" onclick="changeArrow(1);" >
Instructions
</div>
</div>
<div id="Accordion1Content" class="AccordionContent">
<p>Enter in your search parameters by clicking on the title of... </p>
</div>
<div onclick="runAccordion(2);">
<div class="AccordionTitle" id="Accordion2Title" onselectstart="return false;" onclick="changeArrow(2);" >
Colour
</div>
</div>
<div id="Accordion2Content" class="AccordionContent">
[wpv-control field="cultivar-category" type="checkboxes" values="Dark Red" url_param="cultivar-category"]
</div>
</div>
</div>
Javascript:
function changeArrow(index)
{
var arrowID = "Accordian" + index + "Title";
document.getElementById(arrowID).style.background="url(./img/accordian-title-up.png) no-repeat scroll 0 0 transparent";
}
但是,当我单击包含 onclick="runAccordion(index);" 的 div 时,什么也没有发生
我在这里想念什么?
