我对Sharepoint 2013相对比较陌生,我试图用数组内容更新网站列的内容,我可以检索并可视化我的网站列的内容,用户可以更改并保存必要的部分和更改被保存到一个数组中,现在我必须用数组的内容更新网站列的内容,但出于某种原因,我无法完成这些任何建议/示例?这是我的代码到目前为止检索,可视化站点列并将mofication存储到我的数组。SHAREPOINT 2013:如何使用javascript CSOM更新一个数组内容的网站列?

<body> 
     <select id="dropdown" name="dropdown" onchange="optSelect()"> 
      <option value="EngineType_Cylinders">EngineType_Cylinders</option> 
      <option value="EngineType_EngineCycle">EngineType_EngineCycle</option> 
      <option value="EngineType_EngineFamily">EngineType_EngineFamily</option> 
      <option value="EngineType_Euro">EngineType_Euro</option> 
      <option value="EngineType_FamilyEvolution">EngineType_FamilyEvolution</option> 
      <option value="EngineType_GasEmissionLevel">EngineType_GasEmissionLevel</option> 
      <option value="EngineType_Power">EngineType_Power</option> 
      <option value="EngineType_PowerSupply">EngineType_PowerSupply</option> 
      <option value="EngineType_Use">EngineType_Use</option> 
     </select><br /> 

     <textarea id="textareadisplay" rows="25" cols="23"></textarea><br /> 
     <input type ="button" value="Update values" onclick="addItemsToColumns()" /> 
    </body> 

我的JavaScript

$(function() { 
    SP.SOD.executeOrDelayUntilScriptLoaded(Function.createDelegate(this, function() { 
     var select = document.getElementById('dropdown').value; 
     console.log(select); 
     getSiteColumns(select); 

    }), 'SP.js'); 
}); 

var fieldChoice; 
var choices; 
var addFields = []; 
var slc; 
var clientContext; 

function optSelect() { 
    slc = document.getElementById('dropdown').value; 
    getSiteColumns(slc); 
} 

function getSiteColumns(selection) { 
    clientContext = SP.ClientContext.get_current(); 
    if (clientContext != undefined && clientContext != null) { 

     var web = clientContext.get_web(); 

     fieldChoice = clientContext.castTo(web.get_availableFields().getByTitle(selection), SP.FieldChoice); 

     clientContext.load(this.fieldChoice); 
     clientContext.executeQueryAsync(Function.createDelegate(this, this.OnLoadSuccess), Function.createDelegate(this, this.OnLoadFailed)); 
    } 
} 

function OnLoadSuccess(sender, args) { 
    choices = fieldChoice.get_choices(); 
    var textarea = document.getElementById("textareadisplay"); 
    textarea.value = choices.join("\n"); 

} 

function OnLoadFailed(sender, args) { 
    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace()); 
} 

function addItemsToColumns() { 
    clientC = SP.ClientContext.get_current(); 
    var arrayForUpdate = $('#textareadisplay').val().split('\n'); 
    fieldChoice.set_item(, arrayForUpdate); 
    fieldChoice.update(); 
    clientContext.executeQueryAsync(function() { }, function() { }); 


} 

function OnUpdateSuccess(sender, args) { 
    var newchoices = fieldChoice.get_choices(); 

} 

我的问题是关于函数addItemsToColumns(),请帮助!提前致谢。

变形例

以下变形例应达到目的:因为它支持负载

SP.SOD.executeFunc('SP.js', 'SP.ClientContext', function() { 
    var fieldName = $('#dropdown').find(":selected").text(); //get selected column 
    populateValues(fieldName); 
}); 


function populateValues(fieldName) 
{ 
    getFieldChoice(fieldName, 
     function(field){ 
      var values = field.get_choices();    
      $("textarea#textareadisplay").val(values.join("\n")); 
     }, 
     function(sender,args){ 
     console.log(args.get_message()); //handle errors.. 
     }); 
} 



function addItemsToColumns() { 
    var fieldName = $('#dropdown').find(":selected").text(); //get selected column 
    var values = $('textarea#textareadisplay').val().split('\n'); 
    updateFieldChoice(fieldName,values, 
     function(field){ 
     console.log(String.format('{0} field has been updated',fieldName)); 
     }, 
     function(sender,args){ 
     console.log(args.get_message()); //handle errors.. 
     }); 
} 



//SharePoint specific function for getting choice column 
function getFieldChoice(fieldTitle,success,failure) { 
    var ctx = SP.ClientContext.get_current(); 
    var web = ctx.get_web(); 
    var fieldChoice = ctx.castTo(web.get_fields().getByTitle(fieldTitle), SP.FieldChoice); 
    ctx.load(fieldChoice); 
    ctx.executeQueryAsync(
     function(){ 
      success(fieldChoice) 
     }, 
     failure); 
} 

//SharePoint specific function for updating choice column 
function updateFieldChoice(fieldTitle,choiceValues,success,failure) { 
    var ctx = SP.ClientContext.get_current(); 
    var web = ctx.get_web(); 
    var fieldChoice = ctx.castTo(web.get_fields().getByTitle(fieldTitle), SP.FieldChoice); 
    fieldChoice.set_choices(choiceValues); 
    fieldChoice.update(); 
    ctx.executeQueryAsync(
     function(){ 
      success(fieldChoice) 
     }, 
     failure); 
} 

一些建议

  • 不想SP.SOD.executeFuncSP.SOD.executeOrDelayUntilScriptLoaded在 需求脚本
  • 避免全局变量

好,我贴你的代码,我把函数“addItemsToColumns()”的onClick事件,但我的网站列仍然不能用新值更新..当我刷新页面时,网站栏目仍然存在旧的值..我正在努力工作,并让我疯狂。CONSOLE LOG SAYS:此功能对于与列表不相关的字段不可用。 – FabioEnne

啊,请用get_fields()替换函数get_availableFields(),我相信错误会消失(请参阅更新后的答案) –

完成它..但现在它不再显示我的站点列了...... :(...我开始失去对此的所有希望..... – FabioEnne
