我想回显每个块中的每个 ID 和 NAME，但我对 json 很陌生，当我需要读取多个数据时，我总是卡住。感谢您的任何帮助。
假设您显示的 JSON 对象被分配给 JS 变量o并且您希望在 JS 中循环：
for (i = 0; i < o.data.length; i++) {
alert(
'id = ' + o.data[i].id + ''n' +
'name = ' + o.data[i].name + ''n' +
'from.id = ' + o.data[i].from.id + ''n' +
'from.name = ' + o.data[i].from.name
);
}
假设您显示的 JSON 对象被分配为 PHP 字符串变量中的对象$s：
$aObject = json_decode($s, true);
foreach ($aObject['data'] as $i => $a) {
echo
'id = ' . $a['id'] . "<br />'n" .
'name = ' . $a['name'] . "<br />'n" .
'from.id = ' . $a['from']['id'] . "<br />'n" .
'from.name = ' . $a['from']['name'] . "<br /><br />'n'n";
}
顺便说一句，
您正在谈论的ID和名称：在data内部还是在data.from内部
Javascript 方式
var jsondata = {"data": [{ // given string }]};
for (var i=0; i<json.data.length; i++) {
document.write("<hr/><b>"+i+"</b><br/>");
document.write("Data ID=>" + json.data[i].id+";Data Name=> " + json.data[i].name + "<br/>");
document.write(i+"From ID: " + json.data[i].from.id+";From Name:" + json.data[i].from.name );
}
演示
PHP方式
$decodejson = json_decode($jsondata, true);
foreach ($decodejson ['data'] as $k => $v) {
echo
'id =>' . $v['id'] . "<br />'n" .
'name => ' . $v['name'] . "<br />'n" .
'from.id =>' . $v['from']['id'] . "'n" .
'from.name => ' . $v['from']['name'] . "'n";
}
