复选框按钮
$(function() {
//复选框全选控制
var active_class = 'active';
$('#simple-table > thead > tr > th input[type=checkbox]').eq(0).on('click', function(){
var th_checked = this.checked;//checkbox inside "TH" table header
$(this).closest('table').find('tbody > tr').each(function(){
var row = this;
if(th_checked) $(row).addClass(active_class).find('input[type=checkbox]').eq(0).prop('checked', true);
else $(row).removeClass(active_class).find('input[type=checkbox]').eq(0).prop('checked', false);
});
});
});
获取选中的内容
function makeAll(msg){
bootbox.confirm(msg, function(result) {
if(result) {
var str = '';
var emstr = '';
for(var i=0;i < document.getElementsByName('ids').length;i++)
{
if(document.getElementsByName('ids')[i].value!=1){
if(document.getElementsByName('ids')[i].checked){
if(str=='') str += document.getElementsByName('ids')[i].value;
else str += ',' + document.getElementsByName('ids')[i].value;
if(emstr=='') emstr += document.getElementsByName('ids')[i].id;
else emstr += ',' + document.getElementsByName('ids')[i].id;
}
}
}
if(str==''){
bootbox.dialog({
message: "您没有选择任何内容或内容不符!",
buttons:
{ "button":{ "label":"确定", "className":"btn-sm btn-success"}}
});
$("#zcheckbox").tips({
side:3,
msg:'点这里全选',
bg:'#AE81FF',
time:8
});
return;
}else{
if(msg == '确定选中的数据吗?'){
top.jzts();
var diag = new top.Dialog();
diag.Drag=true;
diag.Title ="批量修改";
diag.URL = '<%=basePath%>appointment/editAdmin.do?ids='+emstr;
diag.Width = 600;
diag.Height = 265;
diag.CancelEvent = function(){ //关闭事件
diag.close();
};
diag.show();
后台代码
批量修改我用的是for循环这样会修改几个数据就执行几条sql语句效率比较低，要提高效率可以在xml里面写一个批量修改的sql语句
/**
* 批量修改
* @return
* @throws Exception
*/
@RequestMapping(value="editApp1")
public ModelAndView editApp1() throws Exception{
ModelAndView mv=this.getModelAndView();
PageData pd=this.getPageData();
// appointmentService.listEditApp(pd);
String ids = pd.getString("ids");
String idss[] = ids.split(",");
int user_id=Integer.parseInt((String)pd.get("user_id"));
