So I am testing the permute function of D3.js and it works just fine.
The issue I am having is to display the results on the same page using innerHTML, it always reloads in order to display.
I am probably missing a detail here, can someone help?
permute.html:
<html>
<head>
<meta charset="UTF-8">
<script language="JavaScript">
function* permute(keys) {
var size = keys.length,
c = Array(size).fill(0),
i = 1;
yield keys;
while (i < size) {
if (c[i] < i) {
var k = i % 2 && c[i];
[keys[i], keys[k]] = [keys[k], keys[i]];
c[i]++;
i = 1;
yield keys;
} else {
c[i++] = 0;
}
}
}
function showPermutations(){
var input = document.getElementById("keys").value;
document.getElementById('results').innerHTML=input;
for (var words of permute(input.split(/s+/))) {
document.write(words.join(''));
document.write("<br>");
}
}
</script>
<body>
<form>
<label><b>Keywords</b></label></br>
<input type="text" id="keys" name="keys"></br>
</form>
</br>
<input type="submit" value="Permute" onclick="showPermutations();"></br>
<p><span id='results'></span></p>
</head>
</body>
</html>
Some of you pointed out the issue is caused by the submit button, but in this other example, using submit, the JS works just fine on the same page:
test.html
<html>
<head lang="en">
<meta charset="UTF-8">
<script language="JavaScript">
function showInput() {
document.getElementById('display').innerHTML =
document.getElementById("user_input").value;
}
</script>
</head>
<body>
<form>
<label><b>Enter a Message</b></label>
<input type="text" name="message" id="user_input">
</form>
<input type="submit" onclick="showInput();"><br/>
<label>Your input: </label>
<p><span id='display'></span></p>
</body>
</html>
