javascript中的RegEx仅适用于数字 [英] RegEx in javascript for only numbers

问题描述

我的页面上有文本框(最大长度为2)，该文本框应只包含1-25之间的数字.除空格，字符，-ve值或字母等数字外，我已编写代码将文本框背景更改为黄色，如下所示

I''m having a page with text boxes (with maxlength 2)which should take only numbers from 1-25. Anything except numbers like spaces, characters, -ve values or alphabets etc, i''ve written code to change the textbox background to yellow as below

$("#divBingoKeyIn input:text").each(function () {
                   var currentValue = $(this).attr("value");
                   if (currentValue == "" || parseInt(currentValue) > 25 || parseInt(currentValue) < 1) {
                       $(this).css("background-color", "yellow");
                       isValuesValid = false;
                   }
                   else {
                       $(this).css("background-color", "White");
                   }

但是对于上面的代码，我使用了原始方法来查找它是否不是数字.

我想用下面的简单代码替换它

But for above code i''ve used primitive methods to find if it is not a number.

i would like to replace this with a simple code like below

$("#divBingoKeyIn input:text").each(function () {
                    var currentValue = $(this).attr("value");
                    if (currentValue.match(regex)) {
                        $(this).css("background-color", "yellow");
                        isValuesValid = false;
                    }
                    else {
                        $(this).css("background-color", "White");
                    }

有人可以为我提供上述情况的正则表达式吗?

Can anybody please give me a regex for the above scenario?

推荐答案

(" ).each( function (){ var currentValue =

("#divBingoKeyIn input:text").each(function () { var currentValue =

( this ).attr(" )； 如果(currentValue == " | | parseInt (currentValue)> 25 || parseInt (currentValue)< 1 ){

(this).attr("value"); if (currentValue == "" || parseInt(currentValue) > 25 || parseInt(currentValue) < 1) {

(> ).css(" ， " )； isValuesValid = false ; } 其他 {

(this).css("background-color", "yellow"); isValuesValid = false; } else {
