我只需要一点帮助就可以在我的表单中添加一个简单的加载器/微调器。我的 jquery 中有一个搜索表单。我想在搜索过程中包含加载器/微调器图像。该过程完成后,加载程序将不再可见。
这是我的代码,顺便说一下我正在使用 CodeIgniter。
单击搜索按钮时,这是我的代码:
//search
$('#search-btn').on('click',function(){
var query = $("#keyword").val();
var image = "<?php echo base_url()."/resources/loading/loading43.gif"; ?>";
$('#loading').html(' + image + ');
var query_url = "<?php echo site_url('item_controller/searchItem'); ?>";
$.ajax({
type:'POST',
url: query_url,
data:{query: $("#keyword").val()},
dataType:'json',
async: false,
success:function(d){
//$('.display').dataTable().fnDestroy( true );
$("#example tbody").html(""); //HERE'S MY PROBLEM, DOESN'T DISPLAY LOADER WHEN SEARCHING
for(i in d){
$("#example tbody").append("<tr><td style='text-align: center; color:' data-code='TRUE'>" + d[i]['item_code'] + "</td><td style='text-align: left' data-name='TRUE'>" + d[i]['item_name'] + "</td><td><div style='text-align: center'><input type='button' value='ADD' class='k-button' id='" + d[i]['item_code'] + "' data-item=TRUE /></div></td></tr>");
}
//$("#search_result").show('blind');
$("[data-item]").on('click',function(){
var code = $(this).parents('tr').find('[data-code]').html();
var name = $(this).parents('tr').find('[data-name]').html();
// console.log(code,name);
$("#grid1 tbody").append("<tr><td style='text-align: center; width: 20%'><input type='text' value=" + code + " readonly style='width:50px; background-color: transparent; border-style: none' id=code" + counter_code++ +" /></td><td style='text-align: center; width: 40%'><input type='text' style='width: 90%; background-color: transparent; border-style: none' value='" + name + "' id=item"+ counter_item++ +" readonly /></td><td style='text-align: center'><input type='text' name='qty[]' id=qty"+ counter_qty++ +" style='text-align: center; width: 50px;' /></td><td style='text-align: center'><div align='center'><select style='width:100px; display: block' name='unit[]' id=unit"+ counter_unit++ +" ><option value=''>----</option><option value='pc/pcs'>PC/PCS</option><option value='BOX/BOXES'>BOX/BOXES</option></select></div></td><td style='text-align: center'><input type='text' name='price[]' id=price"+ counter_price++ +" style='text-align: right; width: 100px;' onblur='' /></td><td style='text-align: center'><input type='text' name='total[]' id=total"+ counter_total++ +" style='font-family: courier; text-align: right; background-color: lightgray; color: red; width: 100px;' readonly='readonly' value='' /></td></tr>");
ComputeTotal();
});
$('.display').dataTable({
"bPaginate": true,
"bLengthChange": true,
"bFilter": true,
"bSort": true,
"bInfo": true,
"bAutoWidth": false,
"bDestroy": true,
"bJQueryUI": false,
"bRetrieve": true,
"sPaginationType": "full_numbers",
"iDisplayLength": 25,
"destroy": true
});
//$('.display').dataTable().fnDestroy(true);
//$('.display').children().remove()
},
});
});
这是搜索表格
