$(document).ready(function() {
    $prevent_single_double_quote = function(e) {
        var element = e;
        setTimeout(function() {
            var regexFormat = /^[a-zA-Z0-9 ]*$/;
            var text = element.val();
            if(!regexFormat.test(text)){
                //if contains single or double quotes.
                text = text.substring(0, (text.length-1));
            }
            element.val(text);
        }, 1);
    };
    $('textarea').on('change', function() {
        $prevent_single_double_quote($(this));
    });
    $('textarea').on('keyup', function() {
        $prevent_single_double_quote($(this));
    });
    $('input').on('change', function() {
        $prevent_single_double_quote($(this));
    });
    $('input').on('keyup', function() {
        $prevent_single_double_quote($(this));
    });
    $('.scle').on('keyup', function() {
        $prevent_single_double_quote($(this));
    });
}); 

希望这能奏效！

请尝试这个，这个解决方案是为了防止在输入和粘贴时使用双引号和单引号。

$(document).ready(function() {
$prevent_single_double_quote = function(e) {
    var element = e;
    setTimeout(function() {
        var regexFormat = /^[a-zA-Z0-9\[\]\$\!\#\%\^\&\*\(\)\-\+\=\-\;\:\,\.\?\@\_\' ]*$/;
        var text = element.val();
        if(!regexFormat.test(text)){
            //if contains single or double quotes.
            text = text.substring(0, (text.length-1));
        }
        element.val(text);
    }, 1);
};
$('textarea').on('change', function() {
    $prevent_single_double_quote($(this));
});
$('textarea').on('keyup', function() {
    $prevent_single_double_quote($(this));
});
$('input').on('change', function() {
    $prevent_single_double_quote($(this));
});
$('input').on('keyup', function() {
    $prevent_single_double_quote($(this));
});
$('.scle').on('keyup', function() {
    $prevent_single_double_quote($(this));
});
$( "input" ).bind( 'paste',function()
 {
 var txtbx = $(this);
     setTimeout(function()
     { 
        //get the value of the input text
        var data= $( txtbx ).val() ;
        //replace the special characters to '' 
        var dataFull = data.replace(/((?<![\\])['"])((?:.(?!(?<![\\])\1))*.?)/gi, '');
        //set the new value of the input text without special characters
        $(txtbx).val(dataFull);
     });

  });
  });
