?>javascript - HTML onKeyDown-Event calling function and button-click - Stack Overflow 你的位置:
首页 > programmer > javascript - HTML onKeyDown-Event calling function and button-click - Stack Overflow I'm trying to create a search option.
If someone is using my search field, they can press the "Search-Button" or just press the enter key to start the function.
My problem is that if they press the enter key within the text box it starts my function
and after the function
it calls the button click
.
I've used Google but couldn't solve it, even tried to disable the button while myFunc()
is called.
<!DOCTYPE html>

Where is the myFunc()
code? The most important part of your question

@Jesse the function its self has nothing to do with the question.

Looks like you want to stop the event propagation in this case.
I've changed your code to the following:
<!DOCTYPE html>
<html>
<body>
<form>
Search<br>
<input type="text" id="searchField" onKeyDown="if(event.keyCode==13){console.log('Hello World from Input'); return false;}">
<br>
<button type="button" id="myButton" onClick="console.log('Hello World from Button')">Search</button>
</form>
</body>
</html>
Pressing enter while the input element has the focus gives me only Hello World from Input
at the console.
I think this is what you are asking for: https://jsfiddle/7vf9pz8u/1/
HTML
<form>Search
<br>
<input type="text" id="searchField" onKeyDown="pressEnter()">
<br>
<button type="button" id="myButton" onClick="myFunc()">Search</button>
</form>
JavaScript
function pressEnter() {
if (event.keyCode == 13) {
alert("working");
}
}
Handle the onKeyDown
separately in a function
(onEnter
) and use event.preventDefault();
block the default action.
See the below code.
window.onEnter = function () {
if (event.keyCode == 13) {
event.preventDefault();
return false;
}
}
<form>
Search<br>
<input type="text" id="searchField" onKeyDown="onEnter()">
<br>
<button type="button" id="myButton" onClick="myFunc()">Search</button>
</form>
http://jsfiddle/kishoresahas/cvyzLdy8/
I think you should prevent form submitting by event.preventDefault() in onkeydown function.
I have tested your code in chrome and firefox browser and it is working perfectly as you wish, I make some update in your code to show that it is actually working fine. Follows:
<!DOCTYPE html>
<html>
<body>
<script>
function myFunc(){
alert("Typed text.: "+document.getElementById("searchField").value)
}
</script>
<form>
Search<br>
<input type="text" id="searchField" onKeyDown="if(event.keyCode==13) myFunc()">
<br>
<button type="button" id="myButton" onClick="myFunc()">Search</button>
</form>
</body>
</html>
