我认为,你甚至可以写上你这样的替换线:
$(".someClass option").attr("selected", "selected");
避免<代码>。
这里略微改动了基套式编码,以确保你能够选择子/电文控制,如果你只拥有阶级,而不是id。
<html id="html">
<body id="body">
<script src="file:\D:Sidharthjavascriptjquery-1.4.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
function SelectAll() {
$(".someClass").children().each(function () { $(this).attr("selected", "selected"); });
}
$(".clickme").bind("click", SelectAll);
});
</script>
<input type="submit" class="clickme" />
<select multiple="yes" class="someClass">
<OPTION VALUE="1" id="one">Option 1</OPTION>
<OPTION VALUE="2" id="two">Option 2</OPTION>
<OPTION VALUE="3" id="three">Option 3</OPTION>
<OPTION VALUE="4" id="four">Option 4</OPTION>
</select>
</div>
</body>
</html>
如果你为纽顿或选择发身份证,就用字母编号取代。 例如,如果 but子的id点被点击,而不是仅仅使用板块,而不是像。
希望是你们重新寻找的。
我确信这不是100%,这是你要求的东西,但这里是:
<SELECT MULTIPLE="yes" ID="multipleSelect">
<OPTION VALUE="1" SELECTED="selected">Option 1</OPTION>
<OPTION VALUE="2" SELECTED="selected">Option 2</OPTION>
<OPTION VALUE="3" SELECTED="selected">Option 3</OPTION>
<OPTION VALUE="4" SELECTED="selected">Option 4</OPTION>
<OPTION VALUE="5" SELECTED="selected">Option 5</OPTION>
<OPTION VALUE="6" SELECTED="selected">Option 6</OPTION>
</SELECT>
<INPUT TYPE="submit" ID="submit" value="Go!"/>
动态选择(与 j合):
$("#submit").click(function() {
$("#multipleSelect option").each(function() {
$(this).attr("selected", "selected");
});
});
未经测试。
Good luck.
