（1）OnKeyPress 事件验证 用来验证输入操作
复制代码 代码如下:
function OnKeyPressValidate(obj, event, len) { var e = window.event || event; var key = e.keyCode ? e.keyCode : e.which; var selectedText = ""; if (window.getSelection) { var st = obj.selectionStart; var ed = obj.selectionEnd; selectedText = obj.value.substring(st, ed); } else if (document.selection) { selectedText = document.selection.createRange().text; } if (selectedText != null && selectedText != "") { return true; } var dot = obj.value.indexOf("."); len = (typeof (len) == "undefined") ? 2 : len; if (window.event) { } else { if (key == 8 || key == 9 || key == 46 || (key >= 37 && key <= 40))//for Firefox return true; } if (key <= 57 && key >= 48) { if (dot == -1) return true; else if (obj.value.length <= dot + len) return true; } else if ((key == 46) && dot == -1) { return true; } return false; }
（2）onblur 事件验证 用来验证最终的数据复制代码 代码如下:
function OnBlurValidate(obj, messageId) { var tempValue = trim(obj.value); var message = document.getElementById(messageId); if (tempValue == "") { MessageShow("", message, false); return true; } else { var regu = /^(\d+)(\.?)(\d{0,2})$/; var re = new RegExp(regu); if (!re.test(tempValue)) { MessageShow("Number must be in this format (###.##) or (###)", message, true); return false; } else { MessageShow("", message, false); return true; } } }
