SHAREPOINT 2013:如何读取站点栏内容并通过 javascript csom 修改它们?
SHAREPOINT 2013: How can I read Site column contents and modify them via javascript csom?
我是 Sharepoint 2013 的新手,我正在尝试访问并在页面上显示特定 "Site Column" 中的内容,我已经阅读了很多相关内容,但我仍然无法完成我的任务。到目前为止我得到这个:
'use strict';
var hostweburl;
var appweburl;
$(function () {
SP.SOD.executeOrDelayUntilScriptLoaded(Function.createDelegate(this, function () {
var currentcontext = new SP.ClientContext.get_current();
var web = currentcontext.get_web();
//Get all fields in site collection
var collFields = web.get_availableFields().getByTitle("EngineType_EngineCycle");
currentcontext.load(collFields);
currentcontext.executeQueryAsync(Function.createDelegate(this, ExecuteOnSuccess),
Function.createDelegate(this, ExecuteOnFailure));
}), 'SP.js');
function ExecuteOnSuccess(sender, args)
{
var subsites = '';
//for(int i=0; i< collF {
// if(collFields[i].Title == "siteColumnName"){
// alert("Got the Site col");
// }
//}
}
function ExecuteOnFailure(sender, args) {
alert("error");
}
});
但现在我不知道如何 access/retrieve 我在 CollField 中需要的数据,也许我哪里出错了?请帮忙。非常感谢。
SP.FieldCollection object contains the following methods for getting Field object:
- getById - 获取指定ID的字段
- getByInternalNameOrTitle - returns 具有指定内部名称或标题的第一个字段 object 来自 collection
- getByTitle-returns第一个字段object在collection根据指定字段的标题
例子
以下示例演示如何检索网站栏:
function getSiteField(fieldName,success,failure)
{
var ctx = SP.ClientContext.get_current();
var rootWeb = ctx.get_site().get_rootWeb();
var field = rootWeb.get_availableFields().getByInternalNameOrTitle(fieldName);
ctx.load(field);
ctx.executeQueryAsync(
function(){
success(field)
},
failure);
}
用法
SP.SOD.executeFunc('SP.js', 'SP.ClientContext', function() {
//get Title column and print its properties
getSiteField('Title',
function(field){
//print field properties
console.log(field.get_title());
console.log(field.get_internalName());
console.log(field.get_typeAsString());
console.log(field.get_description());
},
function(sender,args){
console.log(args.get_message());
});
});
如何更新Field object
以下示例演示如何更新 SP.FieldChoice
字段属性:
function updateFieldChoice(fieldTitle,choiceValues,success,failure) {
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var fieldChoice = ctx.castTo(web.get_availableFields().getByTitle(fieldTitle), SP.FieldChoice);
fieldChoice.set_choices(choiceValues);
fieldChoice.update();
ctx.executeQueryAsync(
function(){
success(fieldChoice)
},
failure);
}
用法
var choiceValues = ["Low", "Normal", "Critical"];
updateFieldChoice('RequestStatus',choiceValues,
function(field){
console.log('Choice field has been updated');
},
function(sender,args){
console.log(args.get_message());
});
