使用jquery怎么根据ID给元素赋值

方法/步骤

1

编写页面：

<input type="button" value="按价格" name="score" id="bypic" onclick="bypicord()">

<input type="hidden" value="desc" id="ordercon">

2

编写js:

<script type="text/javascript">

function bypicord(){

var reorder = $("#ordercon").val()

if("desc" == reorder){

$("#ordercon").val("asc")

var url = "<%=path

%>/product/listproduct.action?uid="孝猜+${sessionScope.user.id}+"&sort=price&ten=Y&FROMBUS=Y&order=asc"

gotoquery(url)

//window.location.href =gotoquery('url')

}else {

$("#ordercon").val("desc")

reorder = "desc"

var url = "<%=path

%>/product/listproduct.action?uid="+${sessionScope.user.id}+"&sort=price&ten=Y&FROMBUS=Y&order=desc"

gotoquery(url)

}

}

</script>

其中的：$("#ordercon").val("asc")就是给烂薯id为ordercon的元素赋值

<div id="content"大和></div>

<input id="input" />

<script>

    $("#content").text("填察备写值")

    $("#input").val("填滚没盯写值")

</script>
