Question

我想删除所有空格和特殊字符，并将所有数字放入一个新数组中：var numbers = ['17','9','18','4A'];

这是我正在做的删除空格和特殊字符，但如何把它清理干净并放入数组？

var str = "(17 - 9), (18 - 4A)"
str.replace(/[()-\s]/g, '');

输出："179,184A"

Answer 1

不要把它想象成删除多余的东西，只是把它想象成抓住你想要的东西。

＆＃13;

var input = "(17 - 9), (18 - 4A)";
// Match anything which has one or more numbers or letters in a row
var pattern = /[\da-z]+/gi;
var output = input.match(pattern);
console.log(output);

您可以使用split方法，它返回一个数组：

<div id="userForm"  class="form-horizontal" style="display:none;width:100%;border:solid 0px;" >
        <input ID="btnshowRun" type="button" Value="Show Leave" class="btn btn-warning " style="float:lefts;" OnClick ="showhide();"/>

       <asp:UpdatePanel ID="UpdatePanel5" runat="server" style="display:none;">
            <ContentTemplate>
                <asp:GridView ID="GridView2" runat="server" AllowSorting="False" 
                    AutoGenerateColumns="False" DataKeyNames="EntryID"
                    EmptyDataText="There are no data records to display."
                    ShowFooter="False" HorizontalAlign="Center" OnRowCommand="gvl_RowCommand"
                    ShowHeaderWhenEmpty="True" CssClass="table table-striped table-bordered table-hover table-responsive table-condenseds " Width="100%" GridLines="None">
                    <Columns>
                        <asp:TemplateField HeaderText="Total" SortExpression="Total">
                            <EditItemTemplate>
                                <asp:TextBox ID="tot" runat="server" Text='<%# Bind("Total") %>' class="form-control"></asp:TextBox>
                            </EditItemTemplate>
                            <ItemTemplate>
                                <asp:Label ID="Label4" runat="server" Text='<%# Bind("Total") %>'></asp:Label>
                            </ItemTemplate>
                            <ItemStyle HorizontalAlign="Center" />
                        </asp:TemplateField>
                        <asp:TemplateField ShowHeader="False">
                            <EditItemTemplate>
                                <asp:LinkButton ID="CommandButton" runat="server" CommandArgument='<%# Eval("EntryID") %>' UseSubmitBehaviour=true CausesValidation="False"
                                    CommandName="Update" OnCommand="Updates_Command" Text="Update" class="btn btn-primary btn-sm contrl" Style="margin-right: 10px;"
                                    />
                                &nbsp;<asp:LinkButton ID="Button2" runat="server" CausesValidation="False" CommandName="Cancel" class="btn btn-warning btn-sm contrl" Style="margin-right: 10px;"
                                    Text="Cancel" />
                            </EditItemTemplate>
                            <ItemTemplate>
                                <asp:LinkButton ID="Button1" runat="server" CommandArgument='<%# Eval("EntryID") %>' class="form-control btn btn-default btn-blocks contrl btn-sms"
                                    CommandName="Edit" OnCommand="Button1_Command" Text="Edit" />
                            </ItemTemplate>
                        </asp:TemplateField>
                    </Columns>
                    <HeaderStyle HorizontalAlign="Center" Font-Bold="True" ForeColor="Black"></HeaderStyle>
                </asp:GridView>
            </ContentTemplate>
           </asp:UpdatePanel>
    </div>
