<select name="search_school" id="search_school" onchange="$('#search_school').val() = $('#school_name').val()">
我希望在隐藏的输入中显示所选的选项值
<input type="hidden" name="school_name" id="school_name" value="" />
<select name="search_school" id="search_school" onchange="$('#school_name').val($('#search_school').val())">
当你在没有参数的情况下调用val()时,它会获取元素的值.如果使用val(‘some value’);等参数调用它,则会设置元素的值.
