我将尝试使用CodeIgniter中的onkeyup事件将Number转换为单词。
没有必要阅读更多描述，我只是添加因为StackOverflow没有添加我的问题，因为描述较少。
这是我的观看文件
<label for="name" class="field-wrapper required-field">Enter Amount of
Value:</label>
<?php echo
form_input(['name'=>'price','id'=>'price','onkeyup'=>'myFunction()']); ?>
<div class="col-lg-10">
<?php echo form_error('price',"<p class='text-danger'>","</p>");?>
</div>
<input type="submit" value="Conver Number to Words" name="convert"/>
</div>
<div class="form-group">
<fieldset>
<label class="control-label" for="readOnlyInput">In Words:<br><span
id="demo"></span> </label>
</fieldset>
</div>
<script>
function myFunction() {
var x = document.getElementById("price").value;
document.getElementById("demo").innerHTML = x;
}
</script>
现在，转换为单词功能的数字在我的控制器中，如何发送价值和价值？回到x？
这是我的控制者：
public function pay_number($price)
{
$ones = array(
1 => "one",
2 => "two",
3 => "three",
4 => "four",
5 => "five",
6 => "Six",
7 => "seven",
8 => "eight",
9 => "nine",
10 => "ten",
11 => "eleven",
12 => "twelve",
13 => "thirteen",
14 => "fourteen",
15 => "fifteen",
16 => "sixteen",
17 => "seventeen",
18 => "eighteen",
19 => "nineteen"
);
$tens = array(
2 => "Twenty",
3 => "Thirty",
4 => "Forty",
5 => "Fifty",
6 => "Sixty",
7 => "Seventy",
8 => "Eighty",
9 => "Ninety"
);
$hundreds = array(
"hundred",
"thousand",
"million",
"billion",
"trillion",
"quadrillion"
); //limit t quadrillion
$price = number_format($price,2,".",",");
$num_arr = explode(".",$price);
$wholenum = $num_arr[0];
$decnum = $num_arr[1];
$whole_arr = array_reverse(explode(",",$wholenum));
krsort($whole_arr);
$rettxt = "";
foreach($whole_arr as $key => $i)
{
if($i < 20)
{
$rettxt .= $ones[$i];
}
elseif($i < 100)
{
$rettxt .= $tens[substr($i,0,1)];
$rettxt .= " ".$ones[substr($i,1,1)];
}
else
{
$rettxt .= $ones[substr($i,0,1)]." ".$hundreds[0];
$rettxt .= " ".$tens[substr($i,1,1)];
$rettxt .= " ".$ones[substr($i,2,1)];
}
if($key > 0)
{
$rettxt .= " ".$hundreds[$key]." ";
}
}
if($decnum > 0)
{
$rettxt .= " and ";
if($decnum < 20)
{
$rettxt .= $ones[$decnum];
}
elseif($decnum < 100)
{
$rettxt .= $tens[substr($decnum,0,1)];
$rettxt .= " ".$ones[substr($decnum,1,1)];
}
}
echo $rettxt;
}

您可以使用jquery load(..)。
var x = document.getElementById("price").value;
$("#demo").load( "controller/pay_number/"+x );

使用num2words JQuery插件存档您的需求。我已直接添加了插件代码，您可以将jquery.num2words.js命名为外部文件。
$('#num').focus();
$('#demo').num2words();
$('#demo').num2words({
units: [ "", "One", "Two", "Three", "Four", "Five", "Six","Seven", "Eight", "Nine", "Ten" ],
teens: [ "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen","Sixteen", "Seventeen", "Eighteen", "Nineteen", "Twenty" ],
tens: [ "", "Ten", "Twenty", "Thirty", "Forty", "Fifty", "Sixty","Seventy", "Eighty", "Ninety" ],
othersIntl: [ "Thousand", "Million", "Billion", "Trillion" ]
});<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>
