Question

我想检查我用jquery创建的输入字段。如果有人按下“einenSchritthinzufügen”按钮，jquery将创建div all_steps ，这个结构：

<div class="step">
  <div class="header_step">Schritt '+ (x + 1) +' des Tutorial\'s</div>
  <div class="body_step">
    <a class="create_tutorial_a">Titel des Schrittes</a>
    <input name="input_title_name'+x+'" class="create_tutorial_input" />
    <br>
    <a class="create_tutorial_a">Bild</a><input type="file" />
    <br><br>
    <a class="create_tutorial_a_full_width">Beschreibung des Schrittes</a>
    <br>
    <textarea class="create_tutorial_textarea" name="input_description_name'+x+'">
    </textarea>
  </div>
</div>

这是我的jquery代码：

$(document).ready(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".all_steps"); //Fields wrapper
    var add_button      = $("#add_step"); //Add button ID
    var remove_step     = $("#remove_step");
    
    var x = 0; //initlal text box count
    $(add_button).click(function(){ //on add input button click
        if(x < max_fields){ //max input box allowed
            $(wrapper).append('<div class="step"><div class="header_step">Schritt '+ (x + 1) +' des Tutorial\'s</div><div class="body_step"><a class="create_tutorial_a">Titel des Schrittes</a><input name="input_title_name'+x+'" class="create_tutorial_input" /><br><a class="create_tutorial_a">Bild</a><input type="file" /><br><br><a class="create_tutorial_a_full_width">Beschreibung des Schrittes</a><br><textarea class="create_tutorial_textarea" name="input_description_name'+x+'"></textarea></div>');
            x++; //text box increment
        }
    });
   
    $(remove_step).click(function(){ //user click on remove text
        $('.all_steps .step:last').remove();
        x--;
    });
    
    $(submit).click(function(){
        
    });
});

这是我的HTML代码：

<section>
    <article>
        <div class="step">
            <div class="header_step">Erstelle dein eigenes Tutorial</div>
            <div class="body_step">Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

        </div>
        <form method="post" action="index.php?content=create_tutorial">
        <div class="step">
            <div class="header_step">Allgemeines zum Tutorial</div>
            <div class="body_step">
                <a class="create_tutorial_a">Titel des Tutorial's</a><input class="create_tutorial_input"/>
                <br>
                <a class="create_tutorial_a">Autor des Tutorial's</a><input class="create_tutorial_input"/>
                <br><br>
                <a class="create_tutorial_a_full_width">Beschreibung des Schrittes</a>
                <br>
                <textarea class="create_tutorial_textarea"></textarea>
            </div>
        </div>
        
        <div class="all_steps">
            
        </div>
        
        <div class="step">
            <div class="body_step">
                <input class="create_button" type="button" id="submit" value="Erstellen"/>
                <input type="button" class="create_button" id="add_step" value="Schritt hinzufügen"/>
                <input type="button" class="create_button" id="remove_step" value="Schritt entfernen"/>
            </div>
        </div>
        </form>
        
    </article>
    <div class="clearBoth"></div>
</section>

现在我想检查在按下“erstellen”按钮后用jquery创建的所有字段。如何引用动态创建的输入字段来检查它们？

你可以在步骤中循环使用jQuery，你需要知道每个步骤的索引，看看它如何与下面的代码一起工作

您可以使用第三方jquery插件，例如http://formvalidation.io/，同时检查Validate fields using JQuery validation without any submit?和https://formden.com/blog/validate-contact-form-jquery
