Question

我有一个付款表单，用户将在输入文本字段中输入金额。我有另一个相同形式的文本字段，其中将自动写入用户给出的金额的字数。但我有问题，我如何提取字段的值，并将其传递给将转换值的函数。请帮我。这是用户将提供输入的字段。

    func webViewDidFinishLoad(webView: UIWebView) {

    let webString = webView.request?.URL?.absoluteString
    if (webString! as NSString).containsString("PaymentCCAvenue/ReturnAPI") {

        let html = webView .stringByEvaluatingJavaScriptFromString("document.documentElement.outerHTML")          
        if (html! as NSString).containsString("Success") {
        }
        else if (html! as NSString).containsString("Failure") {  
        }
        else {
        }
    }

}

我有这个字段，价格应自动写入。我尝试了很多方法，但都失败了。

<div class="control-group form-group" style="padding-left:20px; padding-right: 20px;">
                        <div class="controls">
                            <label>Amount</label>
                            <input type="email" class="form-control" name="amount" id="amount" placeholder="Please enter amount"required/>
                        </div>
                    </div>

您的问题似乎是盲目的，请展示您的示例代码，无论如何您可以通过Jquery来完成，

获取该字段值的Jquery：

  var ExtractedValue = $('#YourFieldID').val();

在使用之前必须包含Jquery库。

使用此插件将值转换为金额。：http://www.jqueryscript.net/text/jQuery-Plugin-To-Convert-Numbers-Into-Words-num2words.html

以下是此插件的示例代码。

$(document).ready(function() {
   $('#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" ]
});
