If you write test(TEST123)then it looks for the variable with TEST123name.
so you have to pass it as a string not as a variable
如果你写，test(TEST123)那么它会查找带有TEST123名称的变量。
所以你必须将它作为字符串而不是变量传递
function test(p){
alert(p)
}<a href="#" onclick="test('TEST123')"> and回答by pc_coder
<a href="#" onclick="test('TEST123')">

If you are using select tag, and want to pass the value on selecting the option item, then you can use
如果您使用的是 select 标签，并希望在选择选项项时传递值，那么您可以使用
<select class="form-control" onchange="checkifclick('hello')" name="product_name">
and in javascript,
在 JavaScript 中，
<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.
基本上，我曾经遇到过这个问题，我想调用该函数并将变量传递给该 javascript 函数。
class="form-control"is using to beautify the element, form-controlis a build-in class of bootstrap.
class="form-control"用于美化元素，form-control是bootstrap的内置类。
