// I want to just not let you enter single quotes and double quotes
$('#bot').keypress(function (e) {
var regex = new RegExp("^[a-zA-Z0-9-]+$");
var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
if (regex.test(str)) {
return true;
}
e.preventDefault();
return false;
});
You can use the following Regex :
$('#bot').on('keypress', function (e) {
if (!/['"]/.test(String.fromCharCode(e.keyCode))) {
return;
} else {
e.preventDefault();
}
}); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Digite algo: <textarea id='bot'></textarea> The problem with keypress is that it will not recognize if the data comes from other sources, ie it will not work with Ctrl + V or with the right click of the mouse.
I first recommend using .on('input') and instead of having to check character by character:
String.fromCharCode(!e.charCode ? e.which : e.charCode)
You can simply use .replace in .val() or .value
So:
$('#bot').on('input', function (e) {
this.value = this.value.replace(/['"]/g, "");
}); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Digite algo: <textarea id='bot'></textarea>This will work when you type and when you use Ctrl + V, you will not need to add all events, such as:
.on('keypress') .on('paste') You can do this by just checking the single quotes and quotation marks with a simple if:
$(function(){
$('#bot').keypress(function (e) {
var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
if (str == '"' || str == "'") {
return false;
}
return true;
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><textareaid="bot"></textarea> I do not know what your concern is about the quotes, but you can also replace them with HTML Entities , as follows:
$(function(){
$('#bot').keypress(function (e) {
var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
if (str == '"') {
$(this).html($(this).val() + '"');
return false;
}
if (str == "'") {
$(this).html($(this).val() + ''');
return false;
}
return true;
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><textareaid="bot"></textarea> So the user can use the quotation marks and you will have HTML Entities instead of the quotation marks behind.
