被禁止的单词，但如果有更多的单词则不会 [英] Banned words but not if with more words

问题描述

我找到了解决方案，禁止在输入字段中输入某些单词. 问题是我仅在有人将其用作单个单词时才需要禁止它们，而在输入更多单词时则不需要.

I find solution, to ban some words if they are entered in input field. The problem is that i need ban them only when somebody use them as single word, not when are entered with more words.

示例:

如果输入了％bannedword％，则必须显示ERROR，但是如果有人写

If %bannedword% was entered then ERROR must show up, but if somebody write

％bannedword％wordnotbanned"

" %bannedword% wordnotbanned "

所有标记都必须标记为正确的输入填充，没有任何错误.

all must be marked as correct input fill, without any ERROR.

一切正常后我必须做什么?

What i must do to everything works fine?

这是jQuery

$('#submit').click(function() {

var bannedWords = ["black", "white"],
regex = new RegExp('\\b' + bannedWords.join("\\b|\\b") + '\\b', 'i');
var zalvalid = !regex.test($('#zalmie').val().toLowerCase());

if(!zalvalid) {

    $('#zwynik').addClass("hover").html('<strong>ERROR:</strong>');
    $('#zalmie').focus();
    return false;

} else {

    $('#zwynik').addClass("hover").html('<strong>NICE ONE!</strong>');

}

});

推荐答案

我更改了bannedwords数组，该数组将用于regExp. 您还必须包括用于处理witespaces的方案.因此，我在bannedWords数组中添加了提示.

I have changed the bannedwords array, that will be used for regExp. You must also include the scenario to handle witespaces. So I have added thoes in bannedWords array.

$('#submit').click(function() {

    var bannedWords = ["black ", "white ", "black", "white"],
    regex = new RegExp('\\b' + bannedWords.join("\\b|\\b") + '\\b', 'i');
    var zalvalid = !regex.test($('#zalmie').val().toLowerCase());

if(!zalvalid) {
    $('#zwynik').addClass("hover").html('<strong>ERROR:</strong>');
    $('#zalmie').focus();
    return false;
    } else {
    $('#zwynik').addClass("hover").html('<strong>NICE ONE!</strong>');
    }

});

这是到小提琴的链接！

以前，您无法处理以下情况: 例子:黑色的东西. 因此，您必须具有regExp，它必须能够验证"black"和"white".

Earlier, you were not able to handle the scenario where: Example : black something. So, You must have regExp which must be able to validate "black " and "white " .

如果禁止的单词列表很长，则只需在每个单词之后添加额外的空格.

If your list of banned word is long , then just add extra space after each word.

您还可以自动创建banWord数组.

You can also automate you banWord array creation.
