我有这个代码:
<body>
Please make your selection:
<div id="div1">
<tr>
<td>
<input type="button" value="Insert" onclick="form.html" />
</td>
<td>
<input type="button" value="View" onclick="window.location='view-master.php';" />
</td>
<td>
<input type="button" value="Edit" onclick="edit.html" />
</td>
<td>
<input type="button" value="Search" onclick="showsearchform()" />
</td>
</tr>
</div>
</body>
然后是 JS:
<script type="text/javascript">
function showsearchform()
{
var tr = document.createElement("tr");
var td = document.createElement("td");
var label = document.createElement("label");
label.id = "label1";
label.value = "Surname";
var input = document.createElement("input");
tr.appendChild(td);
td.appendChild(label);
td.appendChild(input);
var element = document.getElementById("div1");
element.appendChild(tr);
$('#input').keyup(function (e) {
var str = $('#search').val();
var url = "search.php";
if (e.keyCode == 13) {
location.href = url;
}
});
}
</script>
当我点击搜索时，我得到了收件箱，但我现在想做的是，当我在框中输入姓氏并按 Enter 键时，我想连接到数据库并搜索这个姓氏
我可以做数据库的事情，只是不确定 JS 和 Jquery
最佳答案
html
<input type="text" name="txt" onkeypress="Search" />
JavaScript
<script>
function Search(e){
if(e.keyCode === 13){// enter key value is 13
**// Your ajax request write here , and in server side you can
**check corresponding results in database and return if data is present and take it as ajax replay****
}
return false;
}
</script>
