我们在所有浏览器中都得到了很好的结果，除了 IE，下面的示例表单。

该表单看起来在 IE 中可以正常运行（表示已成功提交），但结果从未通过。我尝试（分别）删除代码中的所有表，看看是否有帮助，但没有。我对 Javascript 不太了解，但我正在努力解决这个问题。有任何想法吗？验证 ( ) 中的 javaScriptsummation_check_final.js如下：

function validate_input(value,string){
var error = 0;
var reg = /^[\s\d]*$/
if(!reg.test(value)){
        alert(string + ' has to be blank or a number');
        error = 1;
}
return error;
}

function summation(){
var total = 0;
var automotive = $('input[name=Q28_SGVAL_259_SGVAL_1]').val();
total += Number(automotive);
var printing = $('input[name=Q28_SGVAL_269_SGVAL_1]').val();
total += Number(printing);
var hvac = $('input[name=Q28_SGVAL_260_SGVAL_1]').val();
total += Number(hvac); 
var refrigeration = $('input[name=Q28_SGVAL_270_SGVAL_1]').val();
total += Number(refrigeration);        
var conveyors = $('input[name=Q28_SGVAL_261_SGVAL_1]').val();
total += Number(conveyors);

return total;
