SyntaxError: identifier starts immediately after numeric literal. Passing php variable to JavaScript
提问by jlagomarsini
I am trying to pass in two variables to a JavaScript function: the input itself and the user id. I call the function using the onclick attribute of the input.
我试图将两个变量传递给 JavaScript 函数：输入本身和用户 ID。我使用输入的 onclick 属性调用该函数。
echo "<input type = 'submit' class = 'replyButton' id = 'replyButton'
value = 'reply' onclick = 'insertComment(this, $user_id);'>";
The variables go into a JavaScript function:
变量进入 JavaScript 函数：
function insertComment(input, user)
{
//use input and user id to carry out tasks.
}
The error message given is at the function call to 'insertComment()' in the onclick of the input. The error message looks like this:
给出的错误消息是在输入的 onclick 中对“insertComment()”的函数调用。错误消息如下所示：
SyntaxError: identifier starts immediately after numeric literal
insertComment(this, 9f60d869342a);
I have tried multiple quote and dot combinations and have checked the other posts on StackOverFlow. They were all to no avail. Your help in resolving this error is greatly appreciated.
我尝试了多个引号和点组合，并检查了 StackOverFlow 上的其他帖子。他们都无济于事。非常感谢您帮助解决此错误。

you need to quote the user id
您需要引用用户 ID
echo "<input type = 'submit' class = 'replyButton' id = 'replyButton'
value = 'reply' onclick = 'insertComment(this, \"$user_id\");'>";
