jquery实现动态创建form并提交的方法示例

function genSearchObj(url,page,pageSize,keyword){  var params = {};  params.url = url;  params.page = page;  params.pageSize = pageSize;  params.cond = keyword;  return params;}function mockFormSubmit(params){  var form = $('<form />', {action : params.url, method:"post", style:"display:none;"}).appendTo('body');  $.each(params, function(k, v) {     if ( k != "url" ){       form.append('<input type="hidden" name="' + k +'" value="' + v +'" />');     }  });  form.append('<input type="hidden" name="csrfToken" value="' + $("#csrf_token").val() + '" />' );  form.submit();}

var dlform = document.createElement('form');dlform.style = "display:none;";dlform.method = 'post';dlform.action = '../fileServlet';dlform.target = 'callBackTarget';var hdnFilePath = document.createElement('input');hdnFilePath.type = 'hidden';hdnFilePath.name = 'filePath';hdnFilePath.value = filePath;dlform.appendChild(hdnFilePath);document.body.appendChild(dlform);dlform.submit();document.body.removeChild(dlform);
