Question

我需要从dom中的元素id中删除一个字符串（＆＃34; DTE_Field _＆＃34;）。

<select id="DTE_Field_CD_PAIS" dependent-group="PAIS" dependent-group-level="1" class="form-control"></select>

var str=$(el).attr("id");
str.replace("DTE_Field_","");

Answer 1

使用attr() method with callback。这将迭代元素，你可以获得旧的属性值作为回调参数，你可以通过使用 String#replace 方法返回$scope.gridOptions = { rowHeight:60, multiSelect: false, enableColumnMenus:false, enableEdit: false, enableSorting: false, enableFiltering: false, columnDefs: [ { field: 'select', maxWidth: 30, headerCellTemplate:'<div> <div>', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', cellTemplate: '<div class="inner-data-cell"><input type="checkbox"></div>' }, { field: 'status', minWidth: 75, maxWidth: 150, displayName: 'Status', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', 'cellTemplate': '<div class="inner-data-cell">{{row.entity.registrationStatus}}</div>' }, { field: 'name', minWidth: 75, maxWidth: 150, displayName: 'Name', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', cellTemplate: '<div class="inner-data-cell">{{row.entity.lastName}},{{row.entity.firstName}}</div>' }, { field: 'organization', minWidth: 150, displayName: 'Org', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', cellTemplate: '<div class="inner-data-cell">{{row.entity.organization}}</div>' }, { field: 'registratioDate', minWidth: 150, displayName: 'Registration Date', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', cellTemplate: '<div class="inner-data-cell">{{row.entity.registeredOn}}</div>' }, { field: 'lastActive', minWidth: 220, displayName: 'Last Active', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', cellTemplate: '<div class="inner-data-cell">{{row.entity.lastActive}}</div>' }, { field: 'uplaodId', minWidth: 200, displayName: 'Upload Id', headerCellClass: 'grid-header-center', cellClass: 'grid-data-cell', cellTemplate: '<div class="inner-data-cell">NA</div>' } ], filterOptions: $scope.filterOptions };字符串来更新属性。

DTE_FIELD

$('select').attr('id', function(i, oldId) {
  return oldId.replace('DTE_field_', '');
});

$('select').attr('id', function(i, oldId) {
  return oldId.replace('DTE_Field_', '');
});

如果元素并非总是被选中，那么您可以使用 attribute contains selector （或如果<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select id="DTE_Field_CD_PAIS" dependent-group="PAIS" dependent-group-level="1" class="form-control"></select>始终位于开头，则使用 attribute starts with selector < /强>）。

DTE_field_

Answer 2

您可以拆分字符串（.sortLink { /* float:left; */ display: inline-block; }）并使用id方法获取数组的最后一个元素

pop()

Answer 3

像这样使用：

var string=$('#DTE_Field_CD_PAIS').attr("id");
console.log(str.split("DTE_Field_").pop());

Answer 4

$('[id^="DTE_FIELD_"]').each(function () {
   $(this).attr('id', $(this).attr('id').replace('DTE_FIELD_',''));
});
