スペースを文字数としてカウントされないようにする方法

Question

私は検索ボックスを持っており、実際にはかなりうまく動作します。それはあなたが何かをタイプすることです、それが既に存在するなら、それはあなたにトピックを示します。そうでない場合は、このトピックを開くことができるページに移動します。 "ABC"や "ABC"と入力すると大丈夫ですが、 "AB"と入力して検索しようとすると、3文字以上入力する必要があるというエラーが表示されます。しかし、それは簡単に（ "スペーススペース" - 3を数える）のように行うことができます。スペースでトピックを開くことはできますが、そのスペースを数えないようにしてください。 （hello world）など、10文字でカウントする必要があります。文字としてカウントするスペースを除外する方法は？それは私がそれをより良くするために取り組んでいるプロジェクトです、私は自分ですべてを書いていません。ここで

は私の検索ボックスの私はおそらく編集する必要がありますが、方法がわからないすべてのJavaScriptファイルです：

<script type="text/javascript"> 
 
function formatText(tag) { 
 
    var Field = document.getElementById('entry_girdi'); 
 
    var val = Field.value; 
 
    var selected_txt = val.substring(Field.selectionStart, Field.selectionEnd); 
 
    var before_txt = val.substring(0, Field.selectionStart); 
 
    var after_txt = val.substring(Field.selectionEnd, val.length); 
 
\t Field.value += '[' + tag + '/]'; 
 
} 
 
</script>

私の別のトピックは重複しているとマークされていますが、正に言えば、これらの提案された行をjsコードに適応させて正しく動作させる方法はわかりません。

var myString = getElementById("input").value; 
 
var withoutSpace = myString.replace(/ /g,""); 
 
var length = withoutSpace.length;

Answer 1

あなたは自分の場合valには、値をとり、スペースを取り除きます。

変更この行：に

var val = Field.value; 

：

var val = Field.value.replace(/\s/g, ''); 

私は宇宙のすべての種類を一致するあなたは\sで投稿したソリューション、だけではなく、空白から正規表現を変更しましたキャラクター。

Answer 2

あなたはこれで、スペースを含むすべてのcaractersを、数えることができる：

var val = Field.value; 
var chars = val.length; 

を次にあなたが持っているんどのように多くのスペースを数えることができます。最後に

var spacesArr = val.split(" "); 
var spaces = spacesArr.length; 

、あなたが値をsubstract場合、あなたは実際の文字数を持っています：

var actualLength = chars - spaces;
