问题描述

我已经发现了大约UI电网的许多问题autowidth问题。我设法重现其中之一,愿与您分享如何重现它的细节。

首先,我有默认的UI电网隐藏模式里面(你可以找到在这个帖子的末尾code段)。

重现步骤:


  1. 运行code段,preSS启动演示模式; (没有问题);


  2. 关闭模式;


  3. 调整浏览器窗口。这里是。列宽被重置为一个错误值。

解决方案

此外,我想与大家分享修复它的方法。

其实,有两个错误在这里。


  1. UI格设置为0页时,语气是隐藏的调整;

  2. UI格设置为0在页面加载。

第一个是容易察觉,如果你使用的UI电网uncom pressed版本修复:


  

有两个问题的原因是一样的。隐藏的元素的宽度为零。


使用jQuery一个简单的解决方法将是第一种情况如下:

  //调整窗口上的电网调整事件
功能gridResize($事件){
    grid.gridWidth = $ scope.gridWidth = gridUtil.elementWidth($榆树);
    grid.gridHeight = $ scope.gridHeight = gridUtil.elementHeight($榆树);
    的console.log(grid.gridWidth);
    的console.log(grid.gridHeight);
    如果(!$($榆)。是(:隐藏)及和放大器; grid.gridWidth大于0){// if语句前加上这种
        grid.refreshCanvas(真); //这是UI格code
    }
}

第二种情况并非如此简单修复。因为我们需要得到Grid容器的宽度(在这种情况下的模态是容器)。

容器可能是一个隐藏的元素中(这意味着的jQuery(gridContainer).WIDTH()将返回零)。

这是我碰到 jQuery.actual 怎么来的插件(的 github上或的演示)。我会用它给你显示这种特定情况下的解决方案:

  //初始化指令
功能的init(){
    如果($($榆)。是(:隐藏)){//添加
        grid.gridWidth = $ scope.gridWidth = $($榆).parent()实际('宽')。 //添加
    } //添加
    其他{//添加
        grid.gridWidth = $ scope.gridWidth = gridUtil.elementWidth($榆树); //这是UI格code
    } //添加
}

至于结果,我们将得到一个UI电网与适当的自动宽度功能。
最后,我们不需要 $间隔解决方法从的教程这种方法。

I have found many questions about UI Grid autowidth issue. I managed to reproduce one of them and would like to share with you the details on how to reproduce it.

First, I have the default UI Grid inside of a hidden modal (you can find the code snippet at the end of this post).

Steps to reproduce:

  1. Run the code snippet, press "Launch demo modal"; (there is no issues);

  2. Close the modal;

  3. Resize browser window. here it is. Column width is reset to a wrong value.

    var app = angular.module('app', ['ui.grid']);
     
    app.controller('MainCtrl', ['$scope', '$http', 'uiGridConstants', function ($scope, $http, uiGridConstants) {
      $scope.gridOptions1 = {
        enableSorting: true,
        columnDefs: [
          { field: 'name' },
          { field: 'gender' },
          { field: 'company', enableSorting: false }
        ],
        onRegisterApi: function( gridApi ) {
          $scope.grid1Api = gridApi;
        }
      };
     
       
     
     $scope.gridOptions1.data = [
        { name: 1, gender: 2, company: 3 }, 
        { name: 1, gender: 2, company: 3 }, 
        { name: 1, gender: 2, company: 3 }, 
        { name: 1, gender: 2, company: 3 }, 
        { name: 1, gender: 2, company: 3 }];
    }]);

          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
          </div>
        </div>
      </div>
    </div>

解决方案

Also I would like to share with you an approach of fixing it.

Actually, there are two bugs here.

  1. UI Grid is set to 0 on page resize when modal is hidden;
  2. UI Grid is set to 0 on page load.

The first one is easy to detect and fix if you use uncompressed version of UI Grid:

There reason of both issues is the same. The width of hidden element is zero.

A simple workaround with jQuery will be as follows for the first case:

// Resize the grid on window resize events
function gridResize($event) {
    grid.gridWidth = $scope.gridWidth = gridUtil.elementWidth($elm);
    grid.gridHeight = $scope.gridHeight = gridUtil.elementHeight($elm);
    console.log(grid.gridWidth);
    console.log(grid.gridHeight);
    if(!$($elm).is(':hidden') && grid.gridWidth > 0) { //add such if statement before                 
        grid.refreshCanvas(true); //this is UI Grid code
    }
}

The second case is not so simple to fix. Because we need to get the width of Grid container ( in this case modal is the container ).

Container might be inside of a hidden element ( that means jQuery(gridContainer).width() will return zero ).

That is how I came across jQuery.actual plugin (github or demo). I will use it to show you a solution for this specific case:

// Initialize the directive
function init() {
    if($($elm).is(':hidden')) { //added
        grid.gridWidth = $scope.gridWidth = $($elm).parent().actual('width'); //added
    }  //added
    else {  //added
        grid.gridWidth = $scope.gridWidth = gridUtil.elementWidth($elm); //this is UI Grid code
    }  //added
}

As result we will get a UI Grid with proper auto width feature. Finally, we do not need $Interval workaround from the tutorial with this approach.
