Uncaught SyntaxError: Unexpected string
提问by William Isted
I'm having difficulty getting the following to work, all I get from Chrome's Console is Uncaught SyntaxError: Unexpected string.
我很难让以下内容工作，我从 Chrome 的控制台得到的只是Uncaught SyntaxError: Unexpected string.
I have tried tmp = event.keyCodeand changing tmpin the ifstatement to event.keyCodebut I cannot identify the problem.
我已经尝试tmp = event.keyCode并tmp在if声明中更改为，event.keyCode但我无法确定问题所在。
function showSearching() {
alert ("Hello World");
}
$('#search').bind('keydown', function() {
tmp = Number(event.keyCode);
if ( ( tmp=<"48" && tmp=>"90" ) || ( tmp=<"96" && tmp=>"111" ) || ( tmp=<"186" && tmp=>"222" ) ) {
showSearching();
}
});<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
<input id="search" type="text">回答by Adil
Wrong syntax of relational operator in if statement.
if 语句中关系运算符的语法错误。
change => to >=and =< to <=
改变=> to >=和=< to <=
$('#search').bind('keydown', function() {
tmp = Number(event.keyCode);
if ((tmp <= "48" && tmp >= "90") || (tmp <= "96" && tmp >= "111") || (tmp <= "186" && tmp >= "222")) {
showSearching();
}
});?
