Load a Javascript起一定作用,直到空间。
原标题:Load a Javascript function when typing something certain up until a space

For example: When someone types @ it will ready the function.

例如,在“Twitter”上,当有人类型@USERNAME时,即可看出一些情况。 之后,他们没有展示任何东西。

最佳回答

这里的例子有:

document.getElementById( test ).onkeyup = function(oEvent) {
    if (typeof oEvent ==  undefined ) oEvent = window.event;          // IE<9 fix
    if (oEvent.keyCode != 32) return;       // stop if character is not the space
    if (/@USERNAME /.test(this.value)) {      // check if @-template is available
        this.value = this.value.replace(/@USERNAME /g,  Dirk  );    // replace it
    }
}

== UPDATE ==

这里可以选择:

$( #test ).keyup(function(oEvent) {                  // set (keyup) event handler
    if (oEvent.keyCode != 32) return;       // stop if character is not the space
    if (/@USERNAME /.test($(this).val())) {   // check if @-template is available
        $(this).val($(this).val().replace(/@USERNAME /g,  Dirk  )); // replace it
    }
});

也许你可以尝试一个onkeypress关于强制实施空间禁令的活动。
