disabled的使用方法

<tr><th>畅游票价th><td><input type="text" id="pass_price"name="passPrice" onblur="checkPrice();"/>td>tr>

上面onblur对下面的调用事件:

<tr><th>门票区间th><td><select id="purview1" name="purview"disabled="disabled"><option value="0">请选择option>c:forEach items="${spotsPurviewList}"var="spotsPurview" varStatus="vsspotsPurview"><option id="spotsPurview${spotsPurview.keyCode}"

value="${spotsPurview.keyCode}">${spotsPurview.value1}option>

c:forEach>select> <input id="purview"name="purview" type="hidden">td>tr>

Js的使用:(注意大括号的使用)

function checkPrice(){

    var market_price= parseFloat($("#market_price").val());

    $("#market_price").val(market_price);

    var pass_price= parseFloat($("#pass_price").val());

    $("#pass_price").val(pass_price);

    if($("#pass_price").val()== "" ||$("#pass_price").val()<0){#pass_price").val(0);

    }if($("#pass_price").val()>= 0 && $("#pass_price").val() < 50)

    {$("#purview1").val("01");

       $("#purview").val("01");

    }if($("#pass_price").val()>= 50 && $("#pass_price").val() < 100){

       $("#purview1").val("02");

       $("#purview").val("02");

    }      if($("#pass_price").val()>= 100){

       $("#purview1").val("03");

       $( "#purview").val( "03");}}
