Javascript Regarding the Limit Of a Users Input


Javascript Regarding the Limit Of a Users Input

Hope this helps Use onkeypress rather than onkeyup. The keyup event happens too late to prevent the default action.
code :
function validateNumber(event) {
  if (event.target.value > 1000000000) {
    event.preventDefault();
  }
}
<input type="text" onkeypress="validateNumber(event)">

will be helpful for those in need As mentioned by others, if the javascript is only displayed to other users and not run, it would be perfectly safe (not taking into account users manually running the code of course).
If, however, the code is run, then some bad things can happen. One pretty bad thing that can happen is that your site is used to form a so called puppetnet. Puppetnets are similar to botnets but utilize browsers instead, and single puppets may therefore be relatively shortlived (which distinguishes puppetnets from botnets). Puppetnets can be used for distributed denial of service attacks, worm propagation, spamming and more.

Hope this helps I would like to know how to stop the user from inputting numbers into my edittext programmatically, so that it has a similar effect as doing this would
code :
InputFilter filter = new InputFilter() {
    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        String output = "";
        for (int i = start; i < end; i++) {
            if (!Character.isDigit(source.charAt(i))) { 
                    output += source.charAt(i); 
            }
        } 
        return output;
    } 
}; 
edit.setFilters(new InputFilter[]{filter});

hop of those help? You can force the static files to go through the server in order to ensure authentication by setting it up on the web.config:
Web.config
code :
<compilation>
    <buildProviders>
        <add extension=".html" type="System.Web.Compilation.PageBuildProvider" />
        <add extension=".htm" type="System.Web.Compilation.PageBuildProvider" />
         <add extension=".js" type="System.Web.Compilation.ForceCopyBuildProvider"/>
    </buildProviders>
</compilation>

<system.webServer>
     <handlers>
         <add name="HTML" path="*.html" verb="GET, HEAD, POST, DEBUG"   type="System.Web.UI.PageHandlerFactory" resourceType="Unspecified" requireAccess="Script" />
         <add name="HTM" path="*.htm" verb="GET, HEAD, POST, DEBUG" type="System.Web.UI.PageHandlerFactory" resourceType="Unspecified" requireAccess="Script" />
     </handlers>
</system.webServer>
<authorization>
  <allow roles="demo" />
</authorization>
 <authorization>
   <deny users="?" />
 </authorization>

With these it helps You should try to include the if else statements inside the try block with a break statement to exit the while loop if a correct amount is entered.
code :
while True:
    try:
        loan_amount= int(input("How much do you want to borrow?(1000-25000) "))
        if loan_amount > 25000:
            print("Sorry, We only lend up to $25,000. Please try again!")
        else:
            print ("Amount loaned")
            break
    except ValueError:
        print("Sorry, I didn't understand that. Please try again")
How much do you want to borrow?(1000-25000) 24999
Amount loaned

this will help Use a while loop instead of a for loop, break out when you have 10 digits, and refuse to accept any number over 9:
