Javascript 如何删除“；“左”；值引导popover

我需要删除引导弹出框的“左”值。我该怎么做

我不需要在CSS中添加边距或更改左边值，只需要删除它（请检查元素以查看它，它肯定是由bootstrap.js或tooltip.js添加的）

popover的示例：

下面的代码属于bootstrap.js，是关于工具提示/弹出窗口的

function b(b) {
    return this.each(function() {
        var d = a(this),
            e = d.data("bs.tooltip"),
            f = "object" == typeof b && b;
        (e || "destroy" != b) && (e || d.data("bs.tooltip", e = new c(this, f)), "string" == typeof b && e[b]())
    })
}
var c = function(a, b) {
    this.type = this.options = this.enabled = this.timeout = this.hoverState = this.$element = null, this.init("tooltip", a, b)
};
c.VERSION = "3.2.0", c.DEFAULTS = {

    template: '<div class="tooltip" role="tooltip"><div class="tooltip-arrow"></div><div class="tooltip-inner"></div></div>',
    trigger: "hover focus",
    title: "",
    delay: 0,
    html: !1,
    container: !1,
    viewport: {
        selector: "body",
        padding: 0
    }
}, c.prototype.init = function(b, c, d) {
    this.enabled = !0, this.type = b, this.$element = a(c), this.options = this.getOptions(d), this.$viewport = this.options.viewport && a(this.options.viewport.selector || this.options.viewport);
    for (var e = this.options.trigger.split(" "), f = e.length; f--;) {
        var g = e[f];
        if ("click" == g) this.$element.on("click." + this.type, this.options.selector, a.proxy(this.toggle, this));
        else if ("manual" != g) {
            var h = "hover" == g ? "mouseenter" : "focusin",
