js 代码在firefox 和chrome 中不执行

Question

一个gridview中有一个dropdownlist（是否完成：有两个值是和否），当值发生变化时gridview中另一个文本框（完成时间）生成完成时间，或清空。原来是使用AutoPostBack，今天觉得总刷新太麻烦，就是用js写了一段代码，经过调试在IE中正常，但是在firefox 和chrome 不起作用（dropdownlist改变是否完成的值）文本框没变化。请高手赐教。
前台代码：<asp:TemplateField HeaderText="是否解决" SortExpression="是否解决"><ItemStyle width="90px" />
                        <EditItemTemplate>
                            <asp:DropDownList ID="DropDownList4" runat="server"   DataSourceID="SqlDataSource3"
                                DataTextField="YesORNo" DataValueField="YesORNo" SelectedValue='<%# Bind("是否解决") %>' AutoPostBack="False" 
                                onchange="CreatWCRQ()">
                            </asp:DropDownList><asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:xxzxProblemConnectionString %>"
                                SelectCommand="SELECT * FROM [YesORNo]"></asp:SqlDataSource>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="Label13" runat="server" Text='<%# Eval("是否解决") %>'></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField><asp:TemplateField HeaderText="解决时间" SortExpression="解决时间" ><ItemStyle width="100px" />
                        <EditItemTemplate>
                            <asp:TextBox ID="TextBox3" Enabled='<%# FZRIsEdit %>' runat="server" Text='<%# Bind("解决时间", "{0:yyyy-MM-dd}") %>'   onclick="WdatePicker({readOnly:true})"></asp:TextBox>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="Label3" runat="server" Text='<%# Eval("解决时间", "{0:yyyy-MM-dd}") %>' Height="19px" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>js代码：

直接用MS的ScriptManager不是很好吗？也是局部刷新，没有必要写JS
