I am building a form sending function in JavaScript, and I have run into a problem where it executes an else if statement every time. Here is my script:
this.submit = function() {
var url = this.url + "?";
for(el in this.elements) {
var e = $(this.elements[el]);
var n = this.names[el];
if(n === "submit")
{
window.alert("submit");
}
else
{
url += n + "=";
}
if(el == "#dropdown")
{
var options = e.children();
for(var i = 0; i < options.length; i++) {
var option = $('#' + options[i].id);
if(option.attr('selected'))
{
url += option.attr('name');
url += "&";
window.alert("dropdown worked");
break;
}
}
}
else if(el != "#submit") {
url += e.attr('value');
url += "&";
window.alert("input worked");
}
}
window.location.href = url;
};
The problem being that the else if(el != "#submit"){} runs even when the id in question is "#submit". Does anyone know why this doesn't work?
To help, here is my php document, and the rest of the form constructer:
php:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<script src="http://ift.tt/1dLCJcb"></script>
</head>
<body>
<?php if(!$_GET): ?>
<form id="form1">
<input type="text" id="input1" name="name"/>
<br>
<select id="dropdown" name="color">
<option id="null" name="null"></option>
<option id="opt1" name="blue">blue</option>
<option id="opt2" name="yellow">yellow</option>
</select>
<br>
<button type="submit" id="submit" name="submit"onclick="form1.submit()">Submit data</button>
</form>
<script src="http://charlie/form.js"></script>
<script>
var form1 = new form("form1");
form1.setElements();
form1.logElements();
</script>
<?php elseif(!(isset($_GET['name']) || isset($_GET['color']))): ?>
<p style="color:red">ERROR! form.js failed</p>
<?php else: ?>
<p><?= $_GET['name'] ?></p>
<p><?= $_GET['color'] ?></p>
<?php endif; ?>
</body>
</html>
form constructer:
function form(id) {
this.id = "#" + id;
this.url = window.location.href;
this.elements = [];
this.names = [];
this.setElements = function() {
var elements = [],names = [],children = $(this.id).children();
for(var i = 0; i < children.length; i++) {
var childid = children[i].id;
if(childid)
{
elements.push('#' + childid);
}
}
this.elements = elements;
for(var e in this.elements) {
names.push($(this.elements[e]).attr('name'));
}
this.names = names;
};
this.logElements = function() {
for(var e in this.elements) {
console.log(this.elements[e]);
}
for(var n in this.names) {
console.log(this.names[n]);
}
};
this.submit = function() {
var url = this.url + "?";
for(el in this.elements) {
var e = $(this.elements[el]);
var n = this.names[el];
if(n === "submit")
{
window.alert("submit");
}
else
{
url += n + "=";
}
if(el == "#dropdown")
{
var options = e.children();
for(var i = 0; i < options.length; i++) {
var option = $('#' + options[i].id);
if(option.attr('selected'))
{
url += option.attr('name');
url += "&";
window.alert("dropdown worked");
break;
}
}
}
else if(el != "#submit") {
url += e.attr('value');
url += "&";
window.alert("input worked");
}
}
window.location.href = url;
};
}
