Uncaught reference error

and my javascript is,

function test(p){
   alert(p)
}

how can I pass the string>

Answer 1

If you write test(TEST123) then it looks for the variable with TEST123 name.
so you have to pass it as a string not as a variable

 function test(p){ alert(p) } 

 <a href="#" onclick="test('TEST123')"> and 

Answer 2

<a href="#" onclick="test('TEST123')">

只是在您的js函数中写一个字符串参数

Answer 3

If you are using select tag, and want to pass the value on selecting the option item, then you can use

<select class="form-control" onchange="checkifclick('hello')" name="product_name">

and in javascript,

<script>
    function checkifclick(test) {
        alert(test);
    }

Basically, i had faced this problem once, i wanted to call the function and wanted to pass the variables into that javascript function.

class="form-control" is using to beautify the element, form-control is a build-in class of bootstrap.
