SyntaxError：标识符在数字文字后立即启动。将php变量传递给JavaScript [英] SyntaxError: identifier starts immediately after numeric literal. Passing php variable to JavaScript

问题描述

我试图将两个变量传递给JavaScript函数：输入本身和用户标识。我使用输入的onclick属性调用函数。

  echo< input type ='submit'class ='replyButton 'id ='replyButton'
 value ='reply'onclick ='insertComment（this，$ user_id）;'>; 
  

变量进入JavaScript函数：

 函数insertComment（输入，用户）
 {
 //使用输入和用户ID执行任务。 
 
 
 
 
 
 
给出的错误信息是在调用'insertComment（）'的函数中输入的onclick。错误消息如下所示： 
 
 
  SyntaxError：标识符在数字文字后立即启动
 
 insertComment（this ，9f60d869342a）; 
  
我已经尝试了多个报价和点组合，并且检查了StackOverFlow上的其他帖子。他们都无济于事。 
您在解决此错误方面的帮助非常感谢。
解决方案
您需要引用用户标识
  echo< input type ='submit'class ='replyButton'id ='replyButton'
 value ='reply'onclick ='insertComment（this，\$ user_id \）;'>; 
  
 
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.
 echo "<input type = 'submit' class = 'replyButton' id = 'replyButton'
 value = 'reply' onclick = 'insertComment(this, $user_id);'>";
The variables go into a JavaScript function:
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:
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.
解决方案
you need to quote the user id
echo "<input type = 'submit' class = 'replyButton' id = 'replyButton'
 value = 'reply' onclick = 'insertComment(this, \"$user_id\");'>";
