如何使用 javascript 验证动态行 + 选择的 select？

Question

我有下面的代码

http://jsfiddle.net/manojgolty/65xcgaq0/1/

    // Chosenify every multiple select DOM elements with class 'chosen'
    $('.chosen-selects').chosen({
        width: '100%',
        allow_single_deselect : true,
        no_results_text : 'Oops, No Results Found for - '
    });

我从未使用过 JQBootstrapValidator，但您可以改用以下验证器之一：

• BootstrapValidator（不再维护）
• FormValidation（Bootstrapvalidator从v0.6.0起的新名称，是商业产品）
• JQuery-validation.

在您的 fiddle 中，当您生成 select 字段时，您将 Chosen 插件应用到 select 字段，紧接着添加 select 字段到使用的验证器，见以下代码：

# 使用 BootstrapValidator（v0.5.2 或 0.5.3）

$clone.find('select').each(function () {
    // ...
    $(this).chosen({
        // ...
    });
    // <=== Here add your field to BootstrapValidator
    // Revalidate your field when it is changed
    $(this).change(function(e) {
        $('#yourForm').bootstrapValidator('revalidateField', $(this));
    });
    // Add it using the `rules` method
    $('#yourForm').bootstrapValidator('addField', $(this), {
        validators: {
            notEmpty: {
                message: 'Please select an option'
            }
        }
    });
    // ===>
}).end()

然后调用验证器：

$('#yourForm')
    .find('.chosen-selects')
        .chosen({
            width: '100%',
            allow_single_deselect : true,
            no_results_text : 'Oops, No Results Found for - '
        })
        // Revalidate your field when it is changed
        .change(function(e) {
            $('#yourForm').bootstrapValidator('revalidateField', 'your_field_name');
        })
        .end()
    .bootstrapValidator({
        excluded: ':disabled', // <=== make sure to use this option
        feedbackIcons: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            your_field_name: {
                validators: {
                    notEmpty: {
                        message: 'Please choose an option'
                    }
                }
            }
        }
    });

# 使用 FormValidation（v0.6.0 及以上版本）

$clone.find('select').each(function () {
    // ...
    $(this).chosen({
        // ...
    });
    // <=== Here add your field to FormValidation
    // Revalidate your field when it is changed
    $(this).change(function(e) {
        $('#yourForm').formValidation('revalidateField', $(this));
    });
    // Add it using the `rules` method
    $('#yourForm').formValidation('addField', $(this), {
        validators: {
            notEmpty: {
                message: 'Please select an option'
            }
        }
    });
    // ===>
}).end()

然后调用验证器：

$('#yourForm')
    .find('.chosen-selects')
        .chosen({
            width: '100%',
            allow_single_deselect : true,
            no_results_text : 'Oops, No Results Found for - '
        })
        // Revalidate your field when it is changed
        .change(function(e) {
            $('#yourForm').formValidation('revalidateField', 'your_field_name');
        })
        .end()
    .formValidation({
        framework: 'bootstrap',
        excluded: ':disabled', // <=== make sure to use this option
        icon: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            your_field_name: {
                validators: {
                    notEmpty: {
                        message: 'Please choose an option'
                    }
                }
            }
        }
    });

# 使用JQuery-验证

$clone.find('select').each(function () {
    // ...
    $(this).chosen({
        // ...
    });

    // <=== Here add your field to Jquery-validation
    // Revalidate your field when it is changed
    $(this).change(function(e) {
        $(this).valid();
    });
    // Add it using the `rules` method
    $(this).rules( "add", {
        required: true,
        messages: {
            required: "Please select an option"
        }
    });
    // ===>
}).end()

然后调用验证器：

$('#yourForm')
    .find('.chosen-select')
        // Revalidate your field when it is changed
        .change(function(e) {
            $(this).valid();
        })
        .end()
    .validate({
        ignore: ":hidden:not(select)", // <=== make sure to use this option
        rules: {
            your_initial_select_field: {
                required: true
            }
        },
        messages: {
            your_initial_select_field: {
                required: 'Please select an option'
            }
        }
    });
