Question

这是我的页面：

<!DOCTYPE html>
<html>
    <head>
        <title>Loading from DB</title>
    <link rel="stylesheet" href="codebase/webix.css" type="text/css"> 
    <script src="codebase/webix.js" type="text/javascript"></script> 

    </head>
    <body>

<?php
$filename = getcwd() . "/test.txt";
echo $filename;
$line_i_am_looking_for = 5;
$lines = file( $filename , FILE_IGNORE_NEW_LINES );
$lines[$line_i_am_looking_for] = '6my modified line';
file_put_contents( $filename , implode( "\n", $lines ) );
?>



        <div class='header_comment'>Test Button</div>
        <div id="testB" style='height:600px'></div>
        <hr>

        <script type="text/javascript" charset="utf-8">

        webix.ready(function(){

          gridb = webix.ui({
                                container:"testB",
                 "view": "form",
  "elements": [
    {
      "view": "textarea",
      "name": "woNumber",
      "label": "",
      "width": 300,
      "height": 200,
      "options": [
        "onViewResize"
      ],
      "value": "",
      "placeholder": "WO number (separate with comma if several)",
      "labelPosition": "top"
    },
    {
      "view": "button",
      "name": "getWODetails",
      "label": "",
      "value": "Submit",
      "options": [
        "autowidth:true"
      ],
                on:{
                    onItemClick:function(id){
                        webix.message("Test");
                    }
                },
      "labelPosition": "top"

    },
    {
      "view": "button",
      "name": "getWODetails",
      "label": "",
      "value": "Passss",
      "options": [
        "autowidth:true"
      ],
                                on:{
                                        onItemClick:function($filename){
                                                webix.message($filename);
                                        }
                                },
      "labelPosition": "top"

    }

  ]
                        });     



        });


        </script>
    </body>
</html>

现在，我正在尝试添加以下代码以便能够在按下Passss按钮时添加一些字符串：

$filename = getcwd() . "/test.txt";
echo $filename;
$line_i_am_looking_for = 5;
$lines = file( $filename , FILE_IGNORE_NEW_LINES );
$lines[$line_i_am_looking_for] = '6my modified line';
file_put_contents( $filename , implode( "\n", $lines ) );

但如果我这样做，就像下面的样本一样，它不起作用：

on:{
    onItemClick:function($filename){
    $filename = getcwd() . "/test.txt";
    echo $filename;
    $line_i_am_looking_for = 5;
    $lines = file( $filename , FILE_IGNORE_NEW_LINES );
    $lines[$line_i_am_looking_for] = '6my modified line';
    file_put_contents( $filename , implode( "\n", $lines ) );
                                        }

有没有任何线索如何实现？

您需要通过按钮的单击来调用服务器端脚本。像下一个

on:{
    onItemClick:function(){
        webix.ajax().post("save.php");
    }
}

现在，在save.php中，您可以放置必要的逻辑。

如果需要，您可以使用webix.ajax.post的第二个参数向服务器端发送额外的参数

on:{
    onItemClick:function(){
        //will be $_POST["some"] on a server-side
        webix.ajax().post("save.php", { some: this.getValue() });
    }
}

如何将字符串从Webix textarea传递给Button的函数
