asp.net mvc的 - 你怎么通过JavaScript的模型数据环 [英] asp.net mvc - how can you loop through model data in javascript

问题描述

我特林数据添加到在JavaScript中一个列表框，但字符串建筑语法我难住了：

VAR yourobject ='＆LT;％= Model.Inserts ['+ I +']％GT;';

导致错误：字符字符太多字符

所有code的：

  VAR MLB = cm.createListBox（'mylistbox'，{
                        标题：我的列表框，
                        ONSELECT：功能（ⅴ）{
                                tinyMCE.activeEditor.windowManager.alert（'价值选择：'+ V）;
                            }
                        }）;
                        对于（VAR I = 0; I＆LT;'＆LT;％= Model.Inserts.Count（）％GT;';我++）{
                            VAR yourobject ='＆LT;％= Model.Inserts ['+ I +']％GT;';
                            mlb.add（yourobject，I）;
                        }
 

解决方案

您不能混合在服务器上运行（即＆LT的音译code; %%＆GT; 块），在这样的客户端（for循环）上的运行。难道在C＃中的迭代，而不是JavaScript和在一个字符串，你可以简单地分配创建一个JavaScript对象。

 ＆LT;％VAR阿雷=[;
    的foreach（在Model.Inserts变种插入）{
        阿雷+ ='+插入+';
    }
    阿雷= aray.TrimEnd（，）+];
 ％GT;
    VAR MLB = LT;％阿雷％取代;
 

I am tring to add data to a listbox in javascript, however the string building syntax has me stumped:

var yourobject = '<%=Model.Inserts['+ i + ']%>';

causes an error: "Too many characters in character literal"

All of the code:

var mlb = cm.createListBox('mylistbox', {
                        title: 'My list box',
                        onselect: function(v) {
                                tinyMCE.activeEditor.windowManager.alert('Value selected:' + v);
                            }
                        });


                        for (var i = 0; i < '<%=Model.Inserts.Count() %>'; i++) {
                            var yourobject = '<%=Model.Inserts['+ i + ']%>';
                            mlb.add(yourobject, i);
                        }

解决方案

You can't mix code that runs on the server (the transliteration of the <% %> block) with that the runs on the client (the for loop) in that way. Do the iteration in C# rather than in javascript and create a javascript object in a string that you can simply assign.

<%  var aray = "[";
    foreach (var insert in Model.Inserts) {
        aray += "'" + insert + "',";
    }
    aray = aray.TrimEnd(",") + "]";
 %>
    var mlb = <% aray %>;
