Question

我正在使用ajax工作laravel我发送数据到服务器我得到用户然后我不会编辑视图和删除用户我正在使用javascript innerhtml为用户创建一个表，但是当我创建了编辑视图的链接并删除它时，重定向却没有发送数据，而是将变量作为链接发送。

这是我的ajax

<script>
function getstudent(str) {
    var xmlhttp;
    var dep = document.getElementById("department").value;

    if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else { // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = function () {
        if (xmlhttp.readyState == 4) {

            var data = xmlhttp.responseText;
            var obj = JSON.parse(data);
            var x = obj.length;
            var j;

            var table = document.getElementById("myTable");
            var head = document.getElementById("head");
            // table.innerHTML="<tbody> </tbody>"
            head.innerHTML = " <tr> <th>identification</th><th>first name</th><th>last name</th> <th>gfname</th> </tr>"
            //document.getElementById("mytable").innerHTML=' ';
            table.appendChild(head);

            for (j = 0; j <= x; j++) {

                var row = table.insertRow(j + 1);

                // Insert new cells (<td> elements) at the 1st and 2nd position of the "new" <tr> element:
                var cell1 = row.insertCell(0);
                var cell2 = row.insertCell(1);
                var cell3 = row.insertCell(2);
                var cell4 = row.insertCell(3);
                var cell5 = row.insertCell(4);
                var cell6 = row.insertCell(5);
                var cell7 = row.insertCell(6);
                // Add some text to the new cells:
                cell1.innerHTML = obj[j].identification;
                cell2.innerHTML = obj[j].name;
                cell3.innerHTML = obj[j].fname;
                cell4.innerHTML = obj[j].gfname;
                var user = obj[j].id;
                cell5.innerHTML = "<a href='{{ action("
                UserController@show "," + user + ") }}' class='btn btn-default'>View</a>&emsp;";
                cell6.innerHTML = "<a href='{{ action("
                UserController@edit "," + user + ") }}' class='btn btn-default'>View</a>&emsp;";
                cell5.innerHTML = "<a href='{{ action("
                UserController@destroy "," + user + ") }}' class='btn btn-default'>View</a>&emsp;";

            }
        }
    }

    xmlhttp.open("GET", "indexstudget/" + str + "/" + dep, true);
    xmlhttp.send('');
}

这是我观点的一部分

<div class="form-group">
    <label class="col-md-4 control-label">Department</label>
    <div class="col-md-6">
        <select id='department' class="form-control" name="department" onchange="year(this.value)">
            <option>select</option>@foreach( $departments as $department)
            <option name="department" value={{ $department->id }}> {{$department->name}}</option>@endforeach</select>
    </div>
</div>
<br>
<br>
<div class="form-group">
    <label class="col-md-4 control-label">Year</label>
    <div class="col-md-6">
        <select id='demo' name='demo' class="form-control" onchange="getstudent(this.value)">
            <option>select</option>
        </select>
    </div>
</div>@if ( $students->isEmpty() ) There are no students. @else
<table class="table table-striped" id="myTable">
    <thead id="head"></thead>
</table>@endif
<div class="panel-body"> <a href="{{ action('RegistrarController@create') }}" class="btn btn-primary">Create user</a>

    </form>
</div>
</div>

它创建了包含用户正确列表的表，但是当我点击它时，它会发送变量而不是数据

像这样

url http://project/edituser/+user+

Answer 1

我将控制器操作更改为直接路由，并且工作正常。就像这个

"<a href='{{ action("UserController@show","+user+") }}' class='btn btn-default'>View</a>&emsp;"
"<a href='showuser/"+user+"' class='btn btn-default'>View</a>&emsp;"

javascript innerhtml不会将变量发送到链接
