點擊「查找2」按鈕,經過ajax GET方式進行查詢數據,這樣頁面不須要總體刷新,以後清空tbody數據,將查詢結果從新附加到tbodyhtml
前端html:前端
<div class="box-header"> <i class="icon-table"></i> <h5 id="resultcount"> 設備 (共計{{counts}}) </h5> <input style="margin:10px" type="button" id='butupdate' name='Update' value="Update" class="btnc1" style="margin-left:5px;border-bottom: #93bee2 1px solid"> </div> <div class="box-content box-table" id="tablec"> <div class="holder"></div> <form id="searchform" action="" method="get" style="display:inline"> {% csrf_token %} <input type="text" name="q" class="text-search" style="margin-left:42px;display:inline;width: 115px"> <label style="margin-left:10px;display:inline">By</label> <select id="slctsrv" name="slctsrv" style="margin-left:5px;width: 120px"> <option value="APP">應用</option> <option value="IP" selected="selected">IP</option> <option value="ServerName">名稱</option> </select> <input type="button" id="search2" value="查找2" class="btn" style="margin-left:5px"> </form>
前端js:ajax
$("#search2").on("click",function(){ //查找每一個button所在行的td的值 $.ajax({ type: 'GET', //url: '/aptest/', data:$('#searchform').serialize(), dataType:'json', success:function(response,stutas,xhr){ $('#servers tbody').empty(); //清空tbody內容 $('#resultcount').empty(); //清空查詢個數 $("#resultcount").append("設備 (共計" + response.length + ")"); //顯示查詢結果數量 $.each(response,function(i,item){ //response爲返回結果,是一個array,而後對該array進行遍歷,fields屬性中包含全部查詢內容,pk爲每條結果的主鍵字段 var vfields = item.fields var _len=$("#servers tr").length; $("#servers tbody").append("<tr >" //id="+_len+" class='success' +"<td width='2%'><input id='ckbid' name='ckb' type='checkbox'/></td>" +"<td id='num'>"+_len+"</td>" +"<td id='PKID' style='display:none'>" + item.pk +"</td>" +"<td id='APP'>"+ vfields.APP +"</td>" +"<td id='IP'>"+ vfields.IP +"</td>" +"<td id='ServerName'>"+ vfields.ServerName +"</td>" +"<td id='DomainName'>"+ vfields.DomainName +"</td>" +"<td id='CPU'>"+ vfields.CPU +"</td>" +"<td id='MemorySize'>"+ vfields.MemorySize +"</td>" +"<td id='DISK'>"+ vfields.DISK +"</td>" +"<td id='SN'>"+ vfields.SN +"</td>" +"<td id='Type'>"+ vfields.Type +"</td>" +"<td id='OSVersion'>"+ vfields.OSVersion +"</td>" +"<td id='iDRAC'>"+ vfields.iDRAC +"</td>" +"<td id='Rack'>"+ vfields.Rack +"</td>" +"<td id='Person'>"+ vfields.Person +"</td>" +"<td id='Person_app'>"+ vfields.Person_app +"</td>" +"<td id='OS_mark'>" + vfields.OS_mark +"</td>" +"<td><input type='button' id='bbt' value='保存' /></td>" +"</tr>"); $("#ttb").trigger("update"); //sorter }) }, error:function(xhr,errorText,errorStatus){ alert(xhr.status+' error: '+xhr.statusText); }, timeout:5000 }); });
編寫view(Django序列化objects):django
from django.core import serializers #導入serializers模塊 #查詢 if request.method == 'GET': if 'q' in request.GET: q=request.GET['q'] if q is not None: filterconitionname = request.GET['slctsrv'] + '__icontains' srvs = serverinfors.objects.filter(**{filterconitionname:q}) srvs_json = serializers.serialize("json",srvs) return HttpResponse(srvs_json) #將objects過濾結果序列化後返回給ajax接收,對於Jquery來講一個array
print srvs_jsonjson
[{"fields": {"OSVersion": "CentOS", "APP": null,"OS_mark": "Linux"}, "model": "sinfors.serverinfors", "pk": 178}]app
print type(srvs_json) 返回值:‘unicode’url
對srvs_json反序列化:spa
from django.core.serializers import serialize,deserialize deserialize('json',srvs_json) # 返回值是一個迭代器,以下: >> <generator object Deserializer at 0x00000000036A65A0> #查看每一個結果: for i in deserialize('json',sj):print i.object.APP
去掉先後[],方法:srvs_json[1:-1].net
django的 serializers 只支持 queryset,而不支持model的實例code
srvs = serverinfors.objects.get(pk=178) data = serializers.serialize("json",srvs)
錯誤提示:TypeError: 'serverinfors' object is not iterable
解決方式,添加[],以下:
serializers.serialize("json",[srvs])
