我有javascript的问题,对不起,但我不擅长Javascript
我正在尝试,在其他元素上运行cnagecolor,并将颜色传递给我想要的,但没有运气:(
这就是我现在所拥有的
<script>
function changeColor(i) {
var col = document.getElementById("changecolor");
col.style.backgroundColor = '+i+';
}
</script>
<select id="changecolor">
<option>Kategorija</option>
<option onclick="changeColor('rgb(51,51,51)');" style="background-color:rgb(51,51,51);"></option>
<option onclick="changeColor('rgb(0,51,255)');" style="background-color:rgb(0,51,255);"></option>
<option onclick="changeColor('rgb(204,0,153)');" style="background-color:rgb(204,0,153)"></option>
<option onclick="changeColor('rgb(255,204,153)');" style="background-color:rgb(255,204,153)"></option>
</select>

'onclick'事件(以及'onselect')。因此,您可以使用'onchange'代替:
function select_onChange() {
var selectElem = document.getElementById("changecolor");
selectElem.style.backgroundColor = selectElem.value;
}
<select id="changecolor" onchange="select_onChange()">
<option value="rgb(51,51,51)" style="background-color:rgb(51,51,51);">Option #1</option>
<option value="rgb(0,51,255)" style="background-color:rgb(0,51,255);">Option #2</option>
</select>

你可以这样做......
<script>
// Execute this function on change of the select
function changeColor() {
var col = document.getElementById("changecolor");
// Get the value of selected option in select
var values = col.options[col.selectedIndex].value;
col.style.backgroundColor = values;
}
</script>
<select id="changecolor" onchange="changeColor();">
<option>Kategorija</option>
<option value="rgb(51,51,51)">a</option>
<option value="rgb(0,51,255)">v</option>
<option value="rgb(204,0,153)">s</option>
<option value="rgb(255,204,153)">d</option>
</select>
