I have a problem. I want to make server do something after clicking on button. This is my HTML code:
<input name="like" id="like" value="Like" type="submit" />
<script>
$('like').click(function(){
$.post('/test')
});
</script>
and this is my server-side code:
app.post('/test', function (req, res) {
console.log('works');
});
And it doesn't work.
Your problem is here, you have forgotten the # for targeting element by id, so click would never be invoke.
$('#like').click(function(){
$.post('/test');
});
It looks like you aren't selecting the input tag correctly. If you want to select a DOM element by ID, you'll want to use '#IDname' as your selector.
For this example, that means changing it to
...
$('#like').click(function(){
...
This also might not fix the error entirely: using a an input field with a type of "submit", you will likely have to do something like this:
...
$('#like').click(function(e){
e.preventDefault();
...
to keep the default submit event on the input from "bubbling up."
$('#like').click(function(){instead of$('like').click(function(){
