asp.net mvc - Parse all values from a textbox in a method using javascript before sending to the controller -

i have static method here:

public static string parsestringforspecialchars(string stringtoparse) {     const string regexitem = "[^a-za-z0-9 ]";      string stringtoreturn = regex.replace(stringtoparse, regexitem, @"\$%&'");      return stringtoreturn; } 

this method works fine stops many strings being harmful application. suppose there's better way things, that's not point of post.

right want values any textboxes in javascript call method , send data controller.

say have view:

@using myapp.utilities @model list<myapp.models.customerobj>  @{     viewbag.title = "customer index"; }  <h2>customer index</h2>  <p>     @html.actionlink("create new", "create")     @using (html.beginform())     {         <p>             name: @html.textbox("customername") <br/>             address: @html.textbox("customeraddress") city: @html.textbox("customercity") <br/>              <br />             postal code: @html.textbox("customerpc")<br/>             phone number: @html.textbox("customerphone") fax number: @html.textbox("customerfax")<br />             mail: @html.textbox("customeremail")  <br/>             <input type="submit" value="filter" style="float:right">         </p>     } </p> 

how proceed want do? can offers me suggestion how proceed? flexible workaround since view have right change , need method appliable everywhere.

thank you.

have considered adding data annotation model this:

[regularexpression(@"^\$?\d+(\.(\d{2}))?$")] 

this captured from: http://www.asp.net/mvc/tutorials/older-versions/models-%28data%29/validation-with-the-data-annotation-validators-cs

of course, downside have add properties in model want apply to. might able use remote validation , fire off via javascript. otherwise, stuck doing on client side. (but that's not difficult anyway.)
