正則表達式不適用於IE，但適用於其他瀏覽器

Question

(function($){
    $.fn.validationEngineLanguage = function(){
    };
    $.validationEngineLanguage = {
        newLang: function(){
            $.validationEngineLanguage.allRules = {
                "required": { // Add your regex rules here, you can take telephone as an example
                    "regex": "none",
                    "alertText": "This field is required",
                    "alertTextCheckboxMultiple": "Please select an option",
                    "alertTextCheckboxe": "This checkbox is required",
                    "alertTextDateRange": "Both date range fields are required"

                    "alertText": "Invalid phone number"
                },
                "email": {
                    // HTML5 compatible email regex ( http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#    e-mail-state-%28type=email%29 )

                }                               
            };

        }
    };

    $.validationEngineLanguage.newLang();

})(jQuery);

這是我的驗證腳本，但是IE中的圖像失敗，其他瀏覽器沒有問題

            "images": {
                "regex": /^[\w,\s-]+\.[jpg|png|gif]{3}$/,
                "alertText": "Upload .jpg or .png or .gif format"
            },

Answer 1

編寫[pdf]{3}您要匹配['p', 'd', 'f']任何字符，重復三遍。 因此，以下擴展名將有效：

dfp
dpf
fdp
fpd
pdf
pfd

這不是您想要的。

將[pdf]{3}替換為pdf 。

同樣， [jpg|png|gif]{3}應該替換為(jpg|png|gif)

Answer 2

IE會獲取文件的完整路徑，這就是它失敗的原因，因此只需按以下方式編輯正則表達式

/^[\\w,\\s-/\\:]+.(jpg|png|gif)$/
