您可以像这样连接两者:

var pageURL = encodeURIComponent("directory_doctor_page.php?DoctorID=" + frank_param); 

摘自 mozilla 的 JS 文档 String operators :

In addition to the comparison operators, which can be used on string values, the concatenation operator (+) concatenates two string values together, returning another string that is the union of the two operand strings. For example, "my " + "string" returns the string "my string".

The shorthand assignment operator += can also be used to concatenate strings. For example, if the variable mystring has the value "alpha", then the expression mystring += "bet" evaluates to "alphabet" and assigns this value to mystring.
