Question

我使用extension将以下规则添加到现有的jQuery Validate脚本中，但是此片段会导致它破坏而根本不进行验证。我之前和之后尝试了所有可能的逗号组合，并且我也尝试使用mimetypes的accept方法，但到目前为止还没有任何工作。如果我注释掉这个片段（以及它之前的行上的注释），代码就可以正常工作，但添加它会导致它破坏。

Here's a jsFiddle代码按原样（不起作用），here's one代码完全相同，但代码段已被注释掉（工作正常）。

摘录本身：

form1upload: {
    extension: "jpg|jpeg|pdf|doc|docx|png"
}

完整代码：

jQuery(document).ready(function() {
    jQuery("#grantapp").validate({
        errorClass:"errorlabels",
        rules: {
            form1name: "required",
            form1building: "required",
            form1position: "required",
            form1phonex: "required",
            form1besttime: "required",
            form1projtitle: "required",
            form1benefit: "required",
            form1timeframe: "required",
            form1relevance: "required",
            form1description: "required",
            form1amount: "required",
            form1acceptchk: "required",
            form1upload: {
                extension: "jpg|jpeg|pdf|doc|docx|png"
            }
        },
        messages: {
            form1name: "You must enter your name.",
            form1building: "You must enter your building.",
            form1position: "You must enter your position.",
            form1phonex: "You must enter your phone extension.",
            form1besttime: "You must enter the best time to contact you.",
            form1projtitle: "You must give your project a title.",
            form1benefit: "You must enter the number of students who will benefit.",
            form1timeframe: "You must enter a time frame for this project.",
            form1relevance: "<br />You must state how this project is relevant to education.",
            form1description: "<br />You must provide a description of your project.",
            form1amount: "You must enter a requested amount.",
            form1acceptchk: "<span style=\"position:relative;top:-10px;\">You must accept the terms.</span>",
            form1upload: "You may not upload this type of file."
        },
        errorPlacement: function (error, element) { 
            if (element.attr("name") == "form1acceptchk") {
                error.insertAfter("#tbl1");
            } else {
                error.insertAfter(element);
            }
        }
    });
});

这是因为默认情况下the extension rule/method不是jQuery Validate插件的一部分。

如果要使用extension规则，则必须包含jQuery Validate插件的additional-methods.js file。

现在似乎正在运作......
