oracle下拉菜单多选,select multiple 多选列框设置以及显示

“

style="width:210px; height:120px ">

selected="selected">请选择(默认为全选)

selected="selected">1

value="1">2

value="2">3

value="3"selected="selected">4

value="4">5

value="6"selected="selected">6

”

multiple 允许在下拉列表中进行多选，配合size

设置显示大小

BUG一：

var

visitLimit=$("#visitLimits").val();//input text拿到的是字符串所以可以不转化

var

vs=visitLimit.toString();//select拿到的是Long或者Integer形式所以得转换

BUG二：下列代码是显示多选，单选可以用$("id").attr("value",值来显示);

function listColumn(slct){

var commandHtml="";

var str = "";

var sr = slct.split(",")

$.getJSON("visitCusService/listAllColumn.html", {

"userSession.sessionId":sessionId,radom: Math.random() * 100 },

function (json) {

if(json){

if(json.columnList){

commandList

= json.columnList;

$.each(commandList,

function (i) {

var

flag=true;

if(flag){

for(var

j= 0 ;j

if(sr[j]==commandList[i].ID){

str

+= "

" + commandList[i].NAME + "";

flag

=false;

break;

}

}

}

if(flag){

str

+= "" + commandList[i].NAME + "";

}

//str += "" + commandList[i].NAME + "";

});

commandHtml

= str;

}

$("#visitLimits").html(commandHtml);//注意这两者的区别

//$("#visitLimits").append(commandHtml);

commandHtml="";

}else {// json数据异常

alert("数据访问异常");

}

});

}

这里注意
