Python Tkinter条目验证(Python Tkinter Entry validate)

 我正在使用Tkinter在Python 3.6中编写一个程序，其中一个客户有多个（11）输入字段。 我希望这些输入字段只接受整数，并且能够定义最大字符数。 
 

 我已经有一个这样做的功能。 但是这个功能只适用于一个输入字段。 我已经尝试通过调用函数输入变量，以便例如更改另一个输入字段。 我无法做到这一点。 
 

 这是我有1个输入字段的功能。 
 

    def limitMuntgeld(self, *args):
        value = self.invoerM.get()
        if len(value) > 5:
            self.invoerM.set(value[:5])
        if value.lower() in "abcdefghijklmnopqrstuvwxyz-=[];/":
            self.invoerM.set(value[:0])

 

 这是与该函数一起使用的示例输入字段代码 
 

self.invoerMuntgeld = Entry(self, font=('Arial', 14), textvariable=self.invoerM)

 

 这与下面发布的输入字段中的跟踪相结合。 
 

self.invoerM = StringVar()
self.invoerM.trace('w', self.limitMuntgeld)

 

 我也尝试了vcmd和validatecommand。 但是，没有好的结果。 我的endresult将是一个与所有输入字段一起工作的函数。 如果任何人有任何建议，我都耳朵！ 

I am writing a program in Python 3.6 using Tkinter where a customer has multiple(11) entry fields. I want these entry fields to only accept integers and also be able to define the maximum amount of characters.
 

I already have a function that does this. But this function only works for one entry field. I have tried entering variables with calling the function so it changes another entry field for example. I was not able to do this.
 

This is the function I have that works with 1 entry field.
 

    def limitMuntgeld(self, *args):
        value = self.invoerM.get()
        if len(value) > 5:
            self.invoerM.set(value[:5])
        if value.lower() in "abcdefghijklmnopqrstuvwxyz-=[];/":
            self.invoerM.set(value[:0])

 

This is the example entry field code that works with the function
 

self.invoerMuntgeld = Entry(self, font=('Arial', 14), textvariable=self.invoerM)

 

This is combined with a trace on the entry field posted below.
 

self.invoerM = StringVar()
self.invoerM.trace('w', self.limitMuntgeld)

 

I have also tried it with vcmd and validatecommand. However, no good results. My endresult would be one function working with all entry fields. If anyone has any suggestions, I am all ears!

 检查一下。 我改变了var content = []; to var content = {}; 
 

 

 
 
 
  
$(document).on('click', '#guardarBtn', function (event) {
   var content= {};
    $('.rowUpdate').each(function (i) {

        $(this).find('td').each(function (j, v) {
            if (j != 0) {

                var input = $("input", this),
                    name = input.attr("name").substring(0, input.attr("name").length),
                    value = input.val();
                
                    content[name] = value;
            
               // alert(JSON.stringify(content));
            }
        });
       alert(JSON.stringify(content));
       // rows.push(content);
    });

});
 
  
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
    <tr  class="rowUpdate">
        <td>Corredor Feed</td>
        <td>Id Corrdor
            <input type="text" value="" class="validate" name="idcorreo">
        </td>
        <td>Nombre
            <input type="text" value="" class="validate" name="nombre">
        </td>
        <td>Email
            <input type="text" value="foo@bar.com" class="validate" name="email">
        </td>
        <td>Empressa
            <input type="text" value="" class="validate" name="Empressa">
        </td>
        <td>Pagina Web
            <input type="text" value="" class="validate" name="paginaWeb">
        </td>
        <td>Telefono
            <input type="text" value="" class="validate" name="telephon">
        </td>
        <td>Cellular
            <input type="text" value="" class="validate" name="cellular" />
        </td>
        <td>

            <input type="submit" id="guardarBtn" value="Save" name="submitme">
        </td>
    </tr>
</table>
 
 
 

 


Check this one. I changed var content= []; to var content= {}; 
 

 

 
 
 
  
$(document).on('click', '#guardarBtn', function (event) {
   var content= {};
    $('.rowUpdate').each(function (i) {

        $(this).find('td').each(function (j, v) {
            if (j != 0) {

                var input = $("input", this),
                    name = input.attr("name").substring(0, input.attr("name").length),
                    value = input.val();
                
                    content[name] = value;
            
               // alert(JSON.stringify(content));
            }
        });
       alert(JSON.stringify(content));
       // rows.push(content);
    });

});
 
  
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
    <tr  class="rowUpdate">
        <td>Corredor Feed</td>
        <td>Id Corrdor

        </td>
        <td>Nombre

        <td>Email
            <input type="text" value="foo@bar.com" class="validate" name="email">
        </td>
        <td>Empressa
            <input type="text" value="" class="validate" name="Empressa">
        </td>
        <td>Pagina Web

        <td>

            <input type="submit" id="guardarBtn" value="Save" name="submitme">
        </td>
    </tr>
</table>
