但它给
Uncaught reference error
未捕获的参考错误
my html
is 我的
html
是
<a href="#" onclick="test(TEST123)">
and my javascript
is, 我的
javascript
是,
function test(p){
alert(p)
}
how can I pass the string> 我如何传递字符串>
If you write test(TEST123)
then it looks for the variable with TEST123
name. 如果您编写
test(TEST123)
则它将查找具有TEST123
名称的变量。
so you have to pass it as a string not as a variable 因此您必须将其作为字符串而不是变量传递
function test(p){ alert(p) }
<a href="#" onclick="test('TEST123')"> and
<a href="#" onclick="test('TEST123')">
只是在您的js函数中写一个字符串参数
If you are using select tag, and want to pass the value on selecting the option item, then you can use 如果您正在使用选择标签,并且希望在选择选项时传递值,则可以使用
<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,并希望将变量传递给该javascript函数。
