Question

我遇到的情况是我有一个用javascript编写的表单，为详细说明ir name bio等的人创建配置文件。无论如何，我尝试在这个表单中添加一些新字段，但我添加的每个新字段都是当我尝试编辑配置文件信息时抛出“无法识别的表达式”错误。

从“fname”到“owner”的所有字段都很好但是下面的任何字段都会引发错误。与上面的解释一致，“所有者”下面的所有字段都是我最近添加的新字段。

    createForm: function(n) {
        item = $("<table> \
            <tr><th>Name</th><td class='twoinput'><input name='pfname' placeholder='Jane'/><input name='plname' placeholder='Smith'/></tr> \
            <tr><th>Title</th><td><input name='ptitle' placeholder='Chief Executive Officer'/></tr> \
            <tr><th>Short Bio</th><td><textarea name='pbio'/></textarea></td></tr> \
            <tr><th>Photo</th><td><input id='photo_upload' name='photo'/> <input type='button' id='photo_button' value='Open Media Library'/></tr> \
            <tr><td colspan='2'>(Optional) Upload a photo of <acronym title='Replace this with their first name?'>this person</acronym>. The bigger the better&mdash;don't worry, we'll scale this down for you.</td></tr> \
            </table>\
            <br/>\
            <table>\
            <tr><th>Education</th><td><textarea name='pedu'/></textarea></td></tr> \
            <tr><th>Relevant Skills</th><td><textarea name='pskills'/></textarea></td></tr> \
            <tr><th>Professional Experience</th><td><textarea name='pprof'/></textarea></td></tr> \
            <tr><th>Awards & Recognition</th><td><textarea name='pawards'/></textarea></td></tr> \
            <tr><th>Community Involvement</th><td><textarea name='pcommunity'/></textarea></td></tr> \
            <tr><th>Years with the Company</th><td><input type='text' size='2' maxlength='2' name='pyears'/>years</td></tr>\
            <tr><th>Compensation Details</th><td><textarea name='pcompensation'/></textarea></td></tr> \
            </table>\
            <br/>\
            <table>\
            <tr><td id='ownershipquestion' colspan='2'>Does this person have an ownership stake?</td><td id='ownershipbox'><input type='checkbox' id='part_owner' name='owner' value='1'/>Yes</td></tr>\
            <tr><td id='ownershipperquestion' colspan='2'>What percentage does this person hold?</td><td id='ownershipperanswer'><input type='text' size='3' maxlength='3' id='ownership_percentage' name='ownership_percentage'/>%</td></tr>\
        </table>");
        if(n < upsmart.people.people.length) {
            p = upsmart.people.people[n];
            item.find("input[name=pfname]").attr("value",p.fname);
            item.find("input[name=plname]").attr("value",p.lname);
            item.find("input[name=ptitle]").attr("value",p.title);
            item.find("textarea[name=pbio]").attr("value",p.bio);
            item.find("input[name=photo]").attr("value",p.photo);
            item.find("input[name=owner]").attr("value",p.owner);
            item.find("input[name=ownership_percentage]").attr("value",p.ownership_percentage);
            item.find("input[name=pedu").attr("value",p.edu);
            item.find("input[name=pskills").attr("value",p.skills);
            item.find("input[name=pprof").attr("value",p.prof);
            item.find("input[name=pawards").attr("value",p.awards);
            item.find("input[name=pcommunity").attr("value",p.community);
            item.find("input[name=pyears").attr("value",p.years);
            item.find("input[name=pcompensation").attr("value",p.compensation);
        }
        return item;
    },

错误消息的确切措辞示例如下：

错误：语法错误，无法识别的表达式：input [name = pedu

所有相关的javascript函数都可以是viewed here.

提前致谢。

Answer 1

你缺少几个右括号。

item.find("input[name=pedu").attr("value",p.edu);

应该是

item.find("input[name=pedu]").attr("value",p.edu);

Answer 2

你在最后的jQuery选择器中忘记了几个]

编辑：从'pedu'向下，只需添加最后的括号，这应该就是全部。
