Ag-Grid 标头组件添加自定义标头模板 [英] Ag-Grid header Component adding custom header templates

问题描述

我仍在使用 Angular 1.x 和 ag-Grid(非企业).

I'm still using Angular 1.x and ag-Grid (non-enterprise).

但我正在尝试从 angular ui-bootstrap 添加工具提示.所以我需要为所有标题添加一个属性:uib-tooltip='headerValue'"

But I'm trying to add tooltips from angular ui-bootstrap. So I need to add an attribute to all headers: "uib-tooltip='headerValue' "

问题是它想让我实现一个全新的组件.但是他们放在 ag-grid 网站上的示例组件超级复杂，并且与默认功能不同.为什么没有一种简单的方法来做这些事情?

The issue is that it wants me to implement a whole new component. But the example component they put on the ag-grid website is super complicated and different from the default functionality. Why isn't there an easy way of doing these things?

为什么要弃用 headerTemplate?

Why deprecate headerTemplate?

因此，即使我想对默认标头稍作更改，我基本上也需要承担所有责任.而且我什至没有原始版本的标头组件作为示例代码.

So even if I want a slight change from the default headers, I basically need to take over responsibility for everything. And I don't even have the original version of header component as example code.

我只想在不涉及排序、字段、菜单等的标题中添加一些新的 HTML.

I just want to add some new HTML to the header that doesn't involve taking responsibility for sorting, field, menu etc.

推荐答案

我知道这已经过时了，但是......我正是在这种情况下，我想知道为什么没有提供它......我继续建立我自己的，这不是非常困难.因为我认为有人可能会发现一个默认的标头组件很有用:这里有一个本质上是默认的

I know this is old but...I was in this exact situation, where I was wondering why it wasn't provided... I went ahead and built my own which wasn't extremely hard. Since I think someone might find a default header component useful: here's one that is essentially the default

请注意，图标需要字体很棒，并确保在列选项中使用自定义组件.

Note you'll need font awesome for the icons and make sure to use the custom component in your column options.

    function customHeaderComponent() {
    }

    customHeaderComponent.prototype.init = function (agParams) {
        this.agParams = agParams;
        this.eGui = document.createElement('div');

        this.eMenuButton = this.eGui.querySelector(".customHeaderMenuButton");

        if (this.agParams.enableMenu) {

            this.onSortChangedListener = this.onSortChanged.bind(this);

        }
    };

    customHeaderComponent.prototype.getGui = function () {

    };

    customHeaderComponent.prototype.onMenuClick = function () {

    customHeaderComponent.prototype.onSortRequested = function (order, event) {

    customHeaderComponent.prototype.destroy = function () {
        if (this.onMenuClickListener) {
            this.eMenuButton.removeEventListener('click', this.onMenuClickListener)
        }
