用于Wordpress Tooltip插件的Flot麻烦

标签: javascript jquery wordpress tooltip flot

我正在尝试为WordPress的Flot启用工具提示,并且当我添加某个功能时我遇到了问题,我需要根据我试图解读的内容进行操作。

我为flot图表下载了最新版本的工具提示,并在加载插件时加载了脚本。

当代码中没有以下js代码或者函数为空时,我创建的图表加载完美。

有人能告诉我阻止我的图表出现的代码出了什么问题吗?

提前干杯,艾伦。

这是我认为需要使工具提示工作的代码

 function showTooltip(x, y, contents) {
        $("<div id="tooltip">" + contents + "</div>").css({
            position: "absolute",
            display: "none",
            top: y + 5,
            left: x + 20,
            border: "2px solid #4572A7",
            padding: "2px",     
            size: "10",   
            "background-color": "#fff",
            opacity: 0.80
        }).appendTo("body").fadeIn(200);
    }

当我删除代码内部

时,这是有效的
function showTooltip(x, y, contents) {
        position: "absolute"
}

以下完整代码:

答案 0 :(得分:1)

使用javascript时,养成检查调试器控制台是否存在错误的习惯。这是无效的javascript:

$("<div id="tooltip">" + contents + "</div>")

它产生:

SyntaxError: Unexpected identifier

为什么呢?因为没有正确引用。

尝试:

"<div id=\"tooltip\">" + contents + "</div>"

工具提示周围的引号已转义。
