在动态jquery datatable上将sType设置为所有aoColumns [英] Set sType to all aoColumns on dynamic jquery datatable

问题描述

我正在研究一个巨大的自定义datatable函数，我有一个简单的问题，我需要将'sType'设置为所有'aoColumns'，但是这些表是动态的，因此它们可能有6或10列，我找不到办法，我已经尝试了以下选项：

  //不工作
aoColumns：[{sType：string，aTargets：[_all]}]，
 
 //这样做，但它不动态：/ 
aoColumns：{sType：string}，{sType：string}，{sType：string}，{sType：string}，{sType ：string}，{sType：string}]，
  

请使用服务器端执行此操作

obs .:我有一列var数列

  6列
aoColumns：[{sType：string}，{sType：string}，{sType string}，{sType：string}，{sType：string}，{sType：string}]，
 10列
aoColumns [{sType：string}，{sType：string}，{sType：string}，{sType：str sType：string}，{sType：string}，{sType：string}，{sType string}，{sType：string}]，
  

无论如何

解决方案

服务器端PHP：嗯，如果你在php中创建表，那么你应该能够构建一个所有需要的字符串您可以插入到javacript中的数组部分。

 <？php 
 $ colnum = 6; 
 $ i = 1; 
 
 $ aocolumns = array（）; 
 
 while（$ i< = $ colnum）{
 $ aocolumns [] ='{sType：string}' 
 $ i ++; 
} 
 
 $ aocolumns = join（，，$ aocolumns）; 
 $ aocolumns ='['。 $ aocolumns。 ']' 
 
？> 
  

然后将其放在像

 aoColumns：<？= $ aocolumns？> 
  

Javascript：假设您将ajax的列作为一个名为cols的数组，尝试这个循环。 ：

  var aocolumns = []; 
 for（i in cols）{
 var ao = {sType：string}; 
 aocolumns.push（ao）; 
} 
 alert（aocolumns）; 
  

I'm working on a huge custom datatable function and I've a simple issue, I need to set 'sType' to all 'aoColumns', but these tables are dynamic, so they may have 6 or 10 columns, and I can't find a way to do, I have already tried the following options:

//doesn't work
"aoColumns": [{"sType":"string", "aTargets": ["_all"]}],

//this works, but its not dynamic :/
"aoColumns": [{"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}],

and I can't do this using server-side

obs.: I have a var with number of columns

6 columns
"aoColumns": [{"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}],
10 columns
"aoColumns": [{"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}, {"sType":"string"}],

Thanks anyway

解决方案

Server-side PHP: Well, If you are creating the table in php, then you should be able to build a string with all the needed array parts that you can plug into the javacript.

<?php
$colnum = 6;
$i = 1;

$aocolumns = array();

while($i <= $colnum){
  $aocolumns[] = '{"sType":"string"}';
  $i++;
}

$aocolumns = join(",",$aocolumns);
$aocolumns = '[' . $aocolumns . ']';

?>

then drop it in like

"aoColumns": <?=$aocolumns?>

Javascript: Assuming you get the columns back from the ajax as an array called "cols", you can try this for loop. :

var aocolumns = [];
for(i in cols){
  var ao = {"sType":"string"}; 
  aocolumns.push(ao);
}
alert(aocolumns);
