Question

?php foreach($participants as $participant) {
        echo "<tr>";
            echo "<td>" . $participant['Vorname'] . "</td>";
            echo "<td>" . $participant['Auto'] . "<img id=$participant[name_id] onclick='deleteDriver()' class='delete' src='img/tonne.gif' align='right' data-url='backend/queries.php?decision=deleteDriver&id=".$participant['name_id']."'/></td>";

        echo "</tr>";
    }
    ?>

        function deleteDriver()
        {
            var dataString = "decision=deleteDriver";
            $.ajax({
                type: 'POST',
                url: 'queries.php',
                data: dataString
                }
            })
        }
    </script>

当我按下按钮时，不会调用该功能。为什么呢？

Answer 1

formTargetUrl := "www.someVendor.com" formMethod := "POST" fromData := "exampleKey=exampleValue&email=me@something.com&foo=bar" HttpObj := ComObjCreate("WinHttp.WinHttpRequest.5.1") HttpObj.Open(formMethod,formTargetUrl) HttpObj.Send(fromData) rawHtmlResponse := HttpObj.ResponseText ;now you could use regex to find the text, ;you could also dump rawHtmlResponse to a text file, ;or you could use the HTMLfile object if you can identify the html element by its id, name, class, tagname, etc. document := ComObjCreate("HTMLfile") document.write(rawHtmlResponse) textElement := document.getElementById("someId") ;you may also try: ;textElement := document.getElementsByName("someName")[1] ;returns multiple results (not sure if 1 or 0 is the first result) ;textElement := document.getElementsByTagName("someTagName")[1] ;returns multiple results (not sure if 1 or 0 is the first result) ;textElement := document.getElementsByClassName("someClassName")[1] ;returns multiple results (not sure if 1 or 0 is the first result) MsgBox % textElement.innerText ;you may also try ;MsgBox % textElement.textContent ;MsgBox % textElement.innerHTML ;MsgBox % textElement.value之前您错过了<script>开放代码。请添加并重试。请尝试以下方法：

function deleteDriver()

尝试使用此代码。

<?php
    foreach($participants as $participant) {
            echo "<tr>";
                echo "<td>" . $participant['Vorname'] . "</td>";
                echo "<td><a onclick='deleteDriver()'>" . $participant['Auto'] . "<img id=$participant[name_id] class='delete' src='img/tonne.gif' align='right' data-url='backend/queries.php?decision=deleteDriver&id=".$participant['name_id']."'/></a></td>";
           echo "</tr>";
        }
        ?>
      <script>
            function deleteDriver()
            {
                var dataString = "decision=deleteDriver";
                $.ajax({
                    type: 'POST',
                    url: 'queries.php',
                    data: dataString

                })
            }
        </script>

为什么我的onclick函数没有被调用？
