Adding a custom button in row in jqGrid?
提问by jpl
I want to make a simple table that contains a custom button in a row. When the button is pushed, I want to pop up an 'alert' box. I have read some posts on this, for example: this postand this other post, and I don't understand why my code is not working. The buttons are drawn, but pushing them has no effect.
我想制作一个简单的表格，其中包含一个连续的自定义按钮。当按下按钮时，我想弹出一个“警报”框。我已经阅读了一些关于此的帖子，例如： this post和 this other post，我不明白为什么我的代码不起作用。按钮已绘制，但按下按钮无效。
I have three attempts described here.
我在这里描述了三种尝试。
Version 1. The button click never fires:
版本 1. 按钮点击永远不会触发：
$(document).ready(function(){
jQuery("#simpletable").jqGrid({
datatype: "local",
colNames:['A','B','Status'],
colModel:[
{name:'A',index:'A'},
{name:'B',index:'B'},
{name:'status',index:status}
],
data:[
{'A':2,'B':100,'status':"<button onclick=\"jQuery('#simpletable').saveRow('1', function(){alert('you are in')});\" >in</button>"},
{'A':1,'B':200,'status':"<button onclick=\"jQuery('#simpletable').saveRow('2', function(){alert('you are in')});\" >in</button>"},
],
caption: "Demo of Custom Clickable Button in Row",
viewrecords:true,
editurl:'clientArray',
});
});
Html Code:
html代码：
<table id="simpletable"></table>
EDIT 8/2/12 -- I've learned some things since my original post and here I describe two more attempts.
编辑 2012 年 8 月 2 日——自从我的原始帖子以来，我学到了一些东西，在这里我描述了另外两次尝试。
Version 2: I use onCellSelect. This works, but it would not allow me to put more than one button in a cell. Additionally, I made the code nicer by using the format option suggested by one of the comments to this post.
版本 2：我使用 onCellSelect。这有效，但它不允许我在一个单元格中放置多个按钮。此外，我通过使用本文的评论之一建议的格式选项使代码更好。
function status_button_maker_v2(cellvalue, options, rowObject){
return "<button class=\"ver2_statusbutton\">"+cellvalue+"</button>"
};
jQuery("#simpletablev2").jqGrid({
datatype: "local",
colNames:['A','B','Status'],
colModel:[
{name:'A',index:'A'},
{name:'B',index:'B'},
{name:'status',index:status,editable:true,formatter:status_button_maker_v2}
],
data:[
{'A':2,'B':100,'status':"In"},
{'A':1,'B':200,'status':"Out"}
],
onCellSelect:function(rowid,icol,cellcontent,e){
if (icol==2){
alert('My value in column A is: '+$("#simpletablev2").getRowData(rowid)['A']);
}else{
return true;
}
},
caption: "Demo of Custom Clickable Button in Row, ver 2",
viewrecords:true,
}); //end simpletablev2
Markup:
标记：
<style>.ver2_statusbutton { color:blue;} </style>
<h3>simple table, ver 2:</h3>
<table id="simpletablev2"></table>
Version 3: I tried to use the solution to w4ik's post, using ".on" instead of deprecated ".live". This causes the button click to fire, but I don't know how to retrieve the rowid. w4ik also struggled with this, and he posted that he worked it out, but not how he did it. I can get the last row selected, but this will always refer to the previous row selected because the button is taking priority.
版本 3：我尝试使用w4ik 帖子的解决方案，使用“.on”而不是不推荐使用的“.live”。这会导致按钮点击触发，但我不知道如何检索 rowid。w4ik 也为此苦苦挣扎，他发帖说他解决了这个问题，但没有说明他是如何做到的。我可以选择最后一行，但这将始终指选择的前一行，因为按钮优先。
I would prefer this solution if I could get it to work.
如果我可以让它工作，我更喜欢这个解决方案。
jQuery("#simpletablev3").jqGrid({
datatype: "local",
colNames:['A','B','Status'],
colModel:[
{name:'A',index:'A'},
{name:'B',index:'B'},
{name:'status',index:status,editable:true,formatter:status_button_maker_v3}
],
data:[
{'A':2,'B':100,'status':"In"},
{'A':1,'B':200,'status':"Out"}
],
caption: "Demo of Custom Clickable Button in Row, ver 3",
viewrecords:true,
onSelectRow: function(){},
gridComplete: function(){}
}); //end simpletablev3
$(".ver3_statusbutton").on(
{
click: function(){
//how to get the row id? the following does not work
//var rowid = $("#simpletablev3").attr('rowid');
//
//it also does not work to get the selected row
// this is always one click behind:
//$("#simpletablev3").trigger("reloadGrid");
rowid = $("#simpletablev3").getGridParam('selrow');
alert("button pushed! rowid = "+rowid);
}
});
Markup:
标记：
<style>.ver3_statusbutton { color:red;} </style>
<h3>simple table, ver 3:</h3>
<table id="simpletablev3"></table>
In summary, I'm struggling with the issue of getting my button to be pushed at the right time. In version 1, the row gets selected and the button never gets pushed. Version 2 does not use the "button" at all -- It just handles the cell click. Verion 3 gets the button click before the row select (wrong order).
总之，我正在努力解决让我的按钮在正确的时间按下的问题。在版本 1 中，行被选中并且按钮永远不会被按下。版本 2 根本不使用“按钮”——它只是处理单元格点击。版本 3 在行选择之前获得按钮单击（错误的顺序）。
Any help would be appreciated!
任何帮助，将不胜感激！

You can use action formatter here with each row and make edit and delete button as false in formatOptions like this:
您可以在此处对每一行使用操作格式化程序，并在 formatOptions 中将编辑和删除按钮设为 false，如下所示：
formatoptions: {editbutton:false,delbutton:false}}
And follow these two demos:
并遵循以下两个演示：

http://ok-soft-gmbh.com/jqGrid/TestSamle/Admin1.htm
And on click event of these custom buttons show your alert:
在这些自定义按钮的点击事件中显示您的警报：
EDIT
编辑
var getColumnIndexByName = function (grid, columnName) {
var cm = grid.jqGrid('getGridParam', 'colModel'), i, l = cm.length;
for (i = 0; i < l; i++) {
if (cm[i].name === columnName) {
return i; // return the index
}
}
return -1;
},
function () {
var iCol = getColumnIndexByName(grid, 'act');
$(this).find(">tbody>tr.jqgrow>td:nth-child(" + (iCol + 1) + ")")
.each(function() {
$("<div>", {
title: "Custom",
mouseover: function() {
$(this).addClass('ui-state-hover');
},
mouseout: function() {
$(this).removeClass('ui-state-hover');
},
click: function(e) {
alert("'Custom' button is clicked in the rowis="+
$(e.target).closest("tr.jqgrow").attr("id") +" !");
}
}
).css({"margin-right": "5px", float: "left", cursor: "pointer"})
.addClass("ui-pg-div ui-inline-custom")
.append('<span class="ui-icon ui-icon-document"></span>')
.prependTo($(this).children("div"));
});
}
If you check this code, I'm trying to find out index value by giving column name as 'act', you can get index on any other column by giving a different column name.
如果您检查此代码，我正在尝试通过将列名指定为“act”来找出索引值，您可以通过提供不同的列名来获取任何其他列的索引。
var iCol = getColumnIndexByName(grid, 'Demo'); and the rest of the code will be same for you. //demo is the column name where u want to add custom button
and write your click event for this button.
并为此按钮编写单击事件。
Let me know if this works for you or not.
让我知道这是否适合您。
