我在一个php页面中有两个搜索栏,但第二个不起作用。 我有单选按钮组:

<form>
    <p><input type="radio" value="com" name="radioPM" />One</p>  
    <p><input type="radio" value="all" name="radioPM" />Two</p>  
</form>

带有一些jQuery,显示div,具体取决于单选:

<script>
    $(document).ready(function () {
        $('input[type=radio][name=radioPM]').change(function () {
            if (this.value == 'com') {
                $("#comDiv").show();
                $("#allDiv").hide();
            } else if (this.value == 'all') {
                $("#allDiv").show();
                $("#comDiv").hide();
            }
        });
    });
</script>

之后,我有两个div,每个div都位于自己的搜索栏中:

<div id ='comDiv' style="display:none">

    <input type="text" id="myInput" onkeyup="searchByName()" placeholder="search..." title="search...">

    <?php
    include_once('query_1.php');

    echo "<table border='1' id='myTable'>
                    <tr>
                        <th>One</th>
                        <th>Two</th>
                    </tr>";

    while ($row = mysqli_fetch_array($query_1)) {
        echo "<form method=\"post\"><tr>";
        echo "<td>" . $row['ONE'] . "</td>";
        echo "<td>" . $row['TWO'] . "</td>";
        echo "</tr></form>";
    }
    echo "</table>";
    ?><br>

</div>

<div id ='allDiv' style="display:none">

    <input type="text" id="myInput" onkeyup="searchByName()" placeholder="search..." title="search...">

    <?php
    include_once('query_2.php');

    echo "<table border='1' id='myTable'>
                    <tr>
                        <th>One</th>
                        <th>Two</th>
                    </tr>";

    while ($row = mysqli_fetch_array($query_2)) {
        echo "<form method=\"post\"><tr>";
        echo "<td>" . $row['ONE'] . "</td>";
        echo "<td>" . $row['TWO'] . "</td>";
        echo "</tr></form>";
    }
    echo "</table>";
    ?><br>

</div>

最后,我有了带有搜索栏功能的脚本:

<script>
    function searchByName() {
        var input, filter, table, tr, td, i;
        input = document.getElementById("myInput");
        filter = input.value.toUpperCase();
        table = document.getElementById("myTable");
        tr = table.getElementsByTagName("tr");
        for (i = 0; i < tr.length; i++) {
            td = tr[i].getElementsByTagName("td")[1];
            if (td) {
                if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
                    tr[i].style.display = "";
                } else {
                    tr[i].style.display = "none";
                }
            }
        }
    }
</script>

我的问题是,如果我选择第一个选项(value = com)一切正常,则comDiv出现,搜索栏从mysql DB中搜索表。但是,如果我选择第二个选项(value = all),comDiv隐藏,并且allDiv出现,则显示来自mysql DB的数据,但搜索栏不起作用。您能帮我吗,我做错了什么?

id在HTML文档中必须唯一(myInputmyTable两次使用)

您可以像下面那样更新代码或使用conman搜索框

<input type="text" id="myInput1" onkeyup="searchByName('myInput1','myTable1')" placeholder="search..." title="search..."> // id as searchByName parameter 

<input type="text" id="myInput2" onkeyup="searchByName('myInput2','myTable2')" placeholder="search..." title="search...">

<script>
    function searchByName(myInput,myTable) {
        var input, filter, table, tr, td, i;
        input = document.getElementById(myInput);
        filter = input.value.toUpperCase();
        table = document.getElementById(myTable);
        tr = table.getElementsByTagName("tr");
        for (i = 0; i < tr.length; i++) {
            td = tr[i].getElementsByTagName("td")[1];
            if (td) {
                if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
                    tr[i].style.display = "";
                } else {
                    tr[i].style.display = "none";
                }
            }
        }
    }
</script>

并更改表ID echo "<table border='1' id='myTable1'>"<table border='1' id='myTable2'>

我认为您应该在searchByName()函数中提供特定的选择器。因为两个表都具有相同的ID“ myTable”。您应该更改表ID,也可以指定$(“#comDiv”)。find(“ myTable”)和$(“#allDiv”)。find(“ myTable”)
