Question

我收到语法错误：

         Uncaught Syntax Error: missing ) after argument list

表格中的数据似乎显示正常。当我点击表格中的删除按钮时出现错误。但我似乎无法找到代码的任何问题。

它的工作流程是当我点击删除按钮时，它会打开一个模型窗口，询问我是否确定要删除所选的条目，并且一旦我点击是，它应该删除它。但是，当我点击删除按钮时，我会弹出窗口，但是当我在窗口上按“是”时没有任何反应。代码被卡住了。

在主JSP中：

       <div id="subjectArea">

       </div>

       <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content my-popup">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span>
                    <span class="sr-only">Close</span></button>
                <h4 class="modal-title" id="myModalLabel">Delete</h4>
            </div>
            <div class="modal-body">  Are You Sure to Delete? </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-success" id="delete_no" onclick="">Yes</button>  <button type="button" class="btn btn-danger" data-dismiss="modal">No</button>
            </div>
        </div>
    </div>

</div>

<script>
    function changeDeleteId(x) {

        $("#delete_no").attr("onclick","deleteSubjects("+x+")");
    }

在Sub JSP中：

         <table width="100%" id="example" class="table table-bordered" cellspacing="0" style="font-size: 14px ; margin-left: 10px; text-align: center; border: 1px solid black;">

        <%--Table Headers--%>

     <th style="text-align: center">Sr.</th>
     <th style="text-align: center">Code</th>
     <th style="text-align: center">Title</th>
     <th style="text-align: center">Status</th>
     <th style="text-align: center">Actions</th>
      </tr>

     <c:forEach items="${subjects}" var="subject" varStatus="counter">
    <tr style="align-items: center">
        <td style="font-size: 14px ; border: 1px solid black; background-color: white">${counter.count}</td>
        <td style="font-size: 14px ; border: 1px solid black; background-color: white">${subject.subjectCode}</td>
        <td style="font-size: 14px ; border: 1px solid black; background-color: white">${subject.subjectName}</td>
        <td style="font-size: 14px ; border: 1px solid black; background-color: white">${subject.status}</td>
        <td style="font-size: 14px ; border: 1px solid black; background-color: white; text-align: center; margin-left: 20px">
                <%--<a style="color: green; font-weight: bold" href="${pageContext.request.contextPath}/subject/edit/${subject.subjectId}">Edit</a> &nbsp;|&nbsp;--%>
            <a style="text-align: center" href="${pageContext.request.contextPath}/subject/edit/${subject.subjectId}" title="Edit"><i class="fa fa-pencil-square-o edit"></i></a> &nbsp; &nbsp;
            <a data-toggle="modal" data-target="#myModal" style="color: red; font-weight: bold" onclick="changeDeleteId(${subject.subjectId})"><i class="fa fa-trash-o delet"></i></a>
        </td>
    </tr>
</c:forEach>

JavaScript文件：

             function deleteSubjects(x) {
var url = 'delete/' + x;

$.get(url, function(content) {
    $("#subjectArea").html(content);
}).fail(function() {
    alert("Something Went Wrong, Try Again!")
});
}

您粘贴的代码有两个问题：

${subject.subjectId}是一个字符串，它必须作为字符串传递给changeDeleteId函数，即用引号changeDeleteId('${subject.subjectId}')

括起来

$("#delete_no").attr("onclick","deleteSubjects("+x+")");不是将函数绑定到click事件的正确方法。请改用jQuery on()。请参阅其API Doc并查看＆＃34下的示例;将数据传递给处理程序＆＃34;。

最后，您的代码将如下所示：

function changeDeleteId(subjectId) {
   $("#delete_no").on("click", deleteSubjects, {subject: subjectId});
}

function deleteSubjects(event) {
   var url = 'delete/' + event.data.subject;
}
