原标题:function to validate text box on blank or default text
function checkForm(f) {
    if (f.elements[ zoom_query ].value == "" || "Search - Movie or Actor") {
        f.zoom_query.focus();
        return false;
    } else {
        f.submit();
        return false;
    }
}

这阻止了提交任何扼杀文件的格式。

任何想法?

最佳回答

我认为,应该改为:

(f.elements [ zoom_query]. ==“> > ~ Value felements[zoom_query]。

否则,它总是评价真实情况。

function checkForm(f) {

    if (f.zoom_query.value == "" || f.zoom_query.value == "Search - Movie or Actor") {
        alert("Please fill in the text field.");
        f.zoom_query.focus();
        return (false);
    }

    f.submit();
    return (true);
}
