javascript - Validation for accepting numbers and special characters using jQuery

Question

I have written a validation for accepting numbers and special characters but it is accepting only numbers while validating not accepting special characters.

$(document).ready(function () {
$("#law_degree_academic_years").keypress(function (e) {
 if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {
   $("#errmsg").html("Digits Only").show().fadeOut("slow");
           return false;
}
 });
});

<div class="form-group"> 
                                    <label for="law_degree_academic_years" class="col-sm-2 control-label">41. Law Degree Academic Years</label> 
                                    <div class="col-sm-9"> 
                                        <input type="text" class="form-control" value="<?php echo $oppointArr['law_degree_academic_years'];?>" name="law_degree_academic_years" id="law_degree_academic_years" placeholder="Ex:2017-2020" minlegth="9" maxlength="9" required> 
                                    </div> 
                                </div>

Try this method

function Validate() {
        var isValid = false;
        var regex = /^[0-9-+()]*$/;
        isValid = regex.test(document.getElementById("TextBox1").value);
        return isValid;
}
