中。它工作完美......除了在 Internet Explorer 中。 IE 不会给出任何类型的错误,并且我已尽我所能验证代码正在由浏览器执行,但它根本没有任何效果。我创建了这个快速而肮脏的页面来演示这个问题:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head><title></title></head><body>
<table id="employeetable">
<tr>
<th>Name</th>
<th>Job</th>
</tr>
</table>
<script type="text/javascript">
function addEmployee(employeeName, employeeJob) {
var tableElement = document.getElementById("employeetable");
if (tableElement) {
var newRow = document.createElement("tr");
var nameCell = document.createElement("td");
var jobCell = document.createElement("td");
nameCell.appendChild(document.createTextNode(employeeName));
jobCell.appendChild(document.createTextNode(employeeJob));
newRow.appendChild(nameCell);
newRow.appendChild(jobCell);
tableElement.appendChild(newRow);
alert("code executed!");
}
}
setTimeout("addEmployee(\"Bob Smith\", \"CEO\");", 1000);
setTimeout("addEmployee(\"John Franks\", \"Vice President\");", 2000);
setTimeout("addEmployee(\"Jane Doe\", \"Director of Marketing\");", 3000);
</script>
</body></html>
我还没有尝试过 IE 8,但 IE 7 和 IE 6 都没有显示应该添加的附加行。我不明白为什么。有谁知道解决这个问题的好方法,或者我可能做错了什么?
您需要创建一个 TBODY 元素来添加新的 TR,然后将 TBODY 添加到您的表中,如下所示:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head><title></title></head><body>
<table id="employeetable">
<tr>
<th>Name</th>
<th>Job</th>
</tr>
</table>
<script type="text/javascript">
function addEmployee(employeeName, employeeJob) {
var tableElement = document.getElementById("employeetable");
if (tableElement) {
var newTable = document.createElement('tbody'); // New
var newRow = document.createElement("tr");
var nameCell = document.createElement("td");
var jobCell = document.createElement("td");
nameCell.appendChild(document.createTextNode(employeeName));
jobCell.appendChild(document.createTextNode(employeeJob));
newRow.appendChild(nameCell);
newRow.appendChild(jobCell);
newTable.appendChild(newRow); // New
tableElement.appendChild(newTable); // New
alert("code executed!");
}
}
setTimeout("addEmployee(\"Bob Smith\", \"CEO\");", 1000);
setTimeout("addEmployee(\"John Franks\", \"Vice President\");", 2000);
setTimeout("addEmployee(\"Jane Doe\", \"Director of Marketing\");", 3000);
</script>
</body></html>
