本文记录的是在Drupal里实现Click insert textarea效果的方法,如果只是单纯的实现click insert textarea,只需要一段jquery,更复杂的效果,我们可以通过这个实举一反三.
如何在Drupal实现Click insert textarea效果?本教程讲的是单纯的实现click insert textarea的效果,只需一段jquery,它在token.js里的Drupal.behaviors.tokenInsert 函数,改改寻址class就能用了,示例代码如下:
- /**
- * Insert rules to textarea.
- */
- Drupal.behaviors.rulesInsert = {
- attach: function (context, settings) {
- // Keep track of which textfield was last selected/focused.
- $('textarea', context).focus(function() {
- Drupal.settings.sv_rulesFocusedField = this;
- });
- $('.token-click-insert dd', context).once('token-click-insert', function() {
- var newThis = $('<a href="javascript:void(0);" title="' + Drupal.t('Insert this token into your form') + '">' + $(this).html() + '</a>').click(function(){
- if (typeof Drupal.settings.sv_rulesFocusedField == 'undefined') {
- alert(Drupal.t('First click a text field to insert your tokens into.'));
- }
- else {
- var myField = Drupal.settings.sv_rulesFocusedField;
- var myValue = $(this).text();
- //IE support
- if (document.selection) {
- myField.focus();
- sel = document.selection.createRange();
- sel.text = myValue;
- }
- //MOZILLA/NETSCAPE support
- else if (myField.selectionStart || myField.selectionStart == '0') {
- var startPos = myField.selectionStart;
- var endPos = myField.selectionEnd;
- myField.value = myField.value.substring(0, startPos)
- + myValue
- + myField.value.substring(endPos, myField.value.length); //开源软件:Vevb.com
- } else {
- myField.value += myValue;
- }
- $('html,body').animate({scrollTop: $(myField).offset().top}, 500);
- }
- return false;
- });
- $(this).html(newThis);
- });
- }
- };
注:rulesInsert 可自定义,寻址class:.token-click-insert dd 需要改成你的,完整效果参看你安装token模块后插入token的效果.
