问题描述
React 呈现多个跨度,仅使用实际值.有关如何解决此问题的任何建议:
React renders multiple spans, only with the actual value. Any advice on how to fix this:
如果重要的话,用户的名字不应该在一个跨度内,而是作为.chatUser"的innerHTML
And if it matter, the name of the user isn't suppose to be in a span, but as innerHTML of ".chatUser"
实际的渲染方法很短:
createShortUsername: function() {
// shortName is first two letter of first name.
var shortName = this.props.userName.split(" ")[0].slice(0, 2);
console.log(shortName);
return shortName;
},
render: function() {
return (
<div className="chatUser"> {this.createShortUsername()} </div>
);
}
谢谢!
推荐答案
正如@ivarni 所建议的,额外的跨度是由空格引起的!
As suggested by @ivarni, the extra spans were caused by white spaces!
为了防止这种情况,请在括号表达式周围编写没有空格的代码.
To prevent this write your code without white spaces around the braced expressions.
<ReactElement>{noRoomForWhiteSpace}</ReactElement>
