如何解决如何运行onclick函数？ | Java脚本
尝试编写一个脚本，根据搜索栏查找表中的行并返回结果，但运行 onclick 函数时出现问题。我做错了什么？
function tabletoArray(myTable) {
var result = []
var rows = myTable.rows;
var cells,t;
// Iterate over rows
for (var i=0,iLen=rows.length; i<iLen; i++) {
cells = rows[i].cells;
t = [];
// Iterate over cells
for (var j=0,jLen=cells.length; j<jLen; j++) {
t.push(cells[j].textContent);
}
result.push(t);
}
var programs = result.map(function(value,index) { return value[0]; });
var search = document.getElementById('programInput').value.toupperCase();
var wynik = result.filter(function(item){return item[0] === search; });
return wynik;
}
document.write(JSON.stringify(tabletoArray(document.getElementsByTagName('table')[0])));
<input type="text" placeholder="Search..." id="programInput">
<button id="programbutton" type="submit" onclick="tabletoArray(myTable)">Search</button>
<div id="results">
</div>

您无法访问像 myTable.rows 这样的行，因为 myTable 不是 json 对象，而是对 table html 元素的引用。您应该使用 document.queryselectorall 来获取表中的行和列。
,我不认为你可以传递这样的变量。我会在 js 脚本中使用 switch (UrlRead(3)) {
case 'verlogin':
$email = $_POST['email'];
$pass = $_POST['password'];
if ($email == "deneme@deneme.com") {
$Return['STATUS'] = "ERR_USERNAME_TAKEN";
$Return['ERR'] = array(
'email' => 'Username is Taken.'
);
} else {
$Return['STATUS'] = "SUCC";
$Return['ERR'] = array(
'email' => 'Username is available.'
);
}
break;
}
echo json_encode($Return,JSON_UNESCAPED_UNICODE);
作为按钮和表格。然后给按钮添加一个事件监听器。
我可能是错的，但我认为那是你的问题。希望这是有道理的。
