頁面有一個輸入框，輸入框可以動態新增，需求是要拿到所有的輸入框的值然後傳到後臺。

1.頁面放一個原始的輸入框

<label class="control-label" id="AddMoreFileBox" for="form-field-1">新增獎品展示名稱</label>
<div id="InputsWrapper">
    <div><input type="text" name="frontAwardName" id="field_1" value="" placeholder="前端展示獎品文案"/><a href=
 
"#" class="removeclass">刪除</a></div>
</div>

<script>
$(document).ready(function() {
        var MaxInputs       = 8; //maximum input boxes allowed
var InputsWrapper   = $("#InputsWrapper"); //Input boxes wrapper ID
var AddButton       = $("#AddMoreFileBox"); //Add button ID
 
var x = InputsWrapper.length; //initlal text box count
var FieldCount=1; //to keep track of text box added
$(AddButton).click(function (e)  //on add input button click
{
            if(x <= MaxInputs) //max input box allowed
{
                FieldCount++; //text box added increment
                //add input box
 
$(InputsWrapper).append('<div><input type="text" name="frontAwardName" id="field_'+ FieldCount +'" placeholder="前端展示獎品文案 "/><a href="#" class="removeclass">刪除</a></div>');
x++; //text box increment
}
            return false;
});
$("body").on("click",".removeclass", function(e){ //user click on remove text
if( x > 1 ) {
                $(this).parent('div').remove(); //remove text box
x--; //decrement textbox
}
            return false;
})

    });
</script>

function addNewAward() {
    var awardName = $("#awardName").val();
var source = $("#source").val();
var entranceID = $("#entranceID").val();
var frontAwardNameArray = new Array();
$("input[name='frontAwardName']").each(function(){
        frontAwardNameArray.push($(this).val());
});
if(null != awardName && awardName != '' && null != source && null != entranceID){
        $.ajax({
            url:"/jingbean-mng/api/addAwardName?source="+source+"&awardName="+encodeURI(encodeURI(awardName))+"&entranceID="+entranceID+"&frontAwardNameArray="+frontAwardNameArray,
type:"GET",
dataType: "json",
contentType: 'application/json;charset=UTF-8',
success: function (data) {
                if(data){
                    alert("新增獎品名稱成功");
location.href = location.href;
}else{
                    alert("新增獎品名稱失敗");
location.href = location.href;
}
            }
        });
}else{
        alert("請完善資訊後提交");
}
}

4.服務端接收：

@RequestMapping("/addAwardName")
@ResponseBody
public Object addAwardName(String awardName, String source, String entranceID, String [] frontAwardNameArray) {
    if (StringUtils.isNotBlank(awardName) && StringUtils.isNotBlank(source)) {
        try {
            String name = URLDecoder.decode(awardName, "UTF-8");
//bussManageService.addAwardName(name, source);
if (StringUtils.isNotBlank(entranceID)) {
               // bussManageService.addEntranceId(name, entranceID);
}
        } catch (Exception e) {
            logger.error("addAwardName error:" + e);
}
    }
    return 1;
}
