要查看列表字段的名称(Title)和对应的内部名称(InternalName),可以参考官方文档:
function retrieveAllListsAllFields(siteUrl) { var clientContext = new SP.ClientContext(siteUrl); var oWebsite = clientContext.get_web(); var collList = oWebsite.get_lists(); this.listInfoArray = clientContext.loadQuery(collList, ‘Include(Title,Fields.Include(Title,InternalName))‘); clientContext.executeQueryAsync( Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this._onQueryFailed) ); } function onQuerySucceeded() { var listInfo = ‘‘; for (var i = 0; i < this.listInfoArray.length; i++) { var oList = this.listInfoArray[i]; var collField = oList.get_fields(); var fieldEnumerator = collField.getEnumerator(); while (fieldEnumerator.moveNext()) { var oField = fieldEnumerator.get_current(); var regEx = new RegExp(‘name‘, ‘ig‘); if (regEx.test(oField.get_internalName())) { listInfo += ‘\nList: ‘ + oList.get_title() + ‘\n\tField Title: ‘ + oField.get_title() + ‘\n\tField Name: ‘ + oField.get_internalName(); } } } alert(listInfo); } function onQueryFailed(sender, args) { alert(‘Request failed. ‘ + args.get_message() + ‘\n‘ + args.get_stackTrace()); }
