我希望获取值onclick并将其打印在符号"symbol": +sym+
中,
。
检查我的代码:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
</head>
<body>
<p>click here</p>
<!-- TradingView Widget BEGIN -->
<script type="text/javascript" src="https://d33t3vvu2t2yu5.cloudfront.net/tv.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("p").click(function(){
var sym = $(this).val();
alert("alert is working but value is not updating in symbol input");
});
});
new TradingView.widget({
"width": 400,
"height": 450,
"symbol": +sym+,
"interval": "D",
"timezone": "Etc/UTC",
"theme": "White",
"style": "1",
"locale": "en",
"toolbar_bg": "#f1f3f6",
"allow_symbol_change": true,
"hideideas": true,
"show_popup_button": true,
"popup_width": "1000",
"popup_height": "650",
"no_referral_id": true
});
</script>
<!-- TradingView Widget END -->
</body>
</html>

你需要改变:
Map<Group, List<Person>>
到此:
var sym = $(this).val();
或者这个:
var sym = $(this).html();
取决于你想要得到什么。您可能知道var sym = $(this).text();
代码不包含p
属性。

首先,您需要将此 "symbol": +sym+
更改为: "symbol": sym,
。如果你想要实现的是改变变量的价值&#34; sym&#34;在新的&#34; TreadingView.widget&#34;每当你点击段落&#34; p&#34;你做错了。您需要在每次单击元素时更新该值,否则小部件对象将始终保存变量的原始值&#34; sym&#34;,您需要1)更新&#34; sym&#34;值,然后2)重新创建小部件或更新,您可以使用:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
</head>
<body>
<p>click here</p>

$("p").click(function(){
var sym = $(this).text();
new TradingView.widget({

});
alert("alert is working but value is not updating in symbol input");
});
});

试试这个
<script type="text/javascript">
var sym = null;
$(document).ready(function(){
$("p").click(function(){
sym = $(this).text();
alert("alert is working but value is not updating in symbol input");
});
});
setTimeout(function(){
sym = $(this).text();
new TradingView.widget({
"width": 400,
"height": 450,
"symbol": +sym+,
"interval": "D",
"timezone": "Etc/UTC",
"theme": "White",
"style": "1",
"locale": "en",
"toolbar_bg": "#f1f3f6",
"allow_symbol_change": true,
"hideideas": true,
"show_popup_button": true,
"popup_width": "1000",
"popup_height": "650",
"no_referral_id": true
});},5000);
</script>
