我只想在节点创建和节点编辑一种特定内容类型时执行 JavaScript 函数.这只是一个小函数调用.
I would like to execute a JavaScript function only on node creation and node edit of one specific content type. It is only one small function call.
我们将 Drupal 7 内容类型称为tear
",JavaScript 函数称为doitnow();
"
Let's call the Drupal 7 content type "tear
", and the JavaScript function "doitnow();
"
任何想法如何做到这一点?
Any ideas how to do this?
非常感谢.

你必须创建自己的模块并实现 hook_node_insert(), hook_node_update() 和 hook_node_view() 并采取适当的步骤.您还必须使用 Drupal 行为 创建一些 JavaScript 代码,然后您重新准备好.您必须在节点创建/更新后使用临时会话变量,因为这样您可以在 hook_node_view 中检查此变量的存在,并添加告诉"新的撕裂"内容已添加的 JS 设置.
You have to create your own module and implement hook_node_insert(), hook_node_update() and hook_node_view() and take the appropriate steps. You also have to create some JavaScript codes with Drupal behavior, and you're ready. You have to use a temporary session variable after node creation/update, because this way you can check the existance of this variable in hook_node_view, and add the JS setting which "tells" a new "tear" content has been added.
你必须把这个模块放到sites/all/modules/testModule
目录下.
You have to put this module to the sites/all/modules/testModule
directory.
好的,这是模块的代码:
OK, here's the code of the module:
name = Test Customization Module
description = Customizing stuffs on the site...
core = 7.x
package = My modules
scripts[] = js/testModule.behaviors.js
testModule.module
:/**
* Implements hook_node_insert()
*
* @see http://api.drupal.org/api/drupal/modules!node!node.api.php/function/hook_node_insert/7
* @param object $node
*/
function testModule_node_insert($node) {
switch ($node->type) {
case 'tear':
$_SESSION['tear_just_inserted'] = microtime();
break;
}
}
/**
* Implements hook_node_update()
*
* @see http://api.drupal.org/api/drupal/modules!node!node.api.php/function/hook_node_update/7
* @param object $node
*/
function testModule_node_update($node) {
switch ($node->type) {
case 'tear':
$_SESSION['tear_just_inserted'] = microtime();
break;
}
}
/**
* Implements hook_node_view().
*/
function testModule_node_view($node, $view_mode, $langcode) {
switch ($node->type) {
case 'tear':
// we call doitnow() if it's needed (if "tear" content was added before)
if (isset($_SESSION['tear_just_inserted'])) {
drupal_add_js(array('testModule' => array('tear_just_added' => TRUE)), 'setting');
unset($_SESSION['tear_just_inserted']);
}
break;
}
}
/**
* Implements hook_overlay_child_initialize()
* @see http://api.drupal.org/api/drupal/modules!overlay!overlay.api.php/function/hook_overlay_child_initialize/7
*/
function testModule_overlay_child_initialize() {
// Add our custom JavaScript: we don't want the node/add/tear to appear on the overlay, because this way the JS setting doesn't get added properly
drupal_add_js(drupal_get_path('module', 'testModule') . '/js/testModule.overlay.behaviors.js');
}
js/testModule.behaviors.js
:(function ($) {
Drupal.behaviors.testModule = {
doitnow: function(){
alert("A new "tear" content has just been added!");
},
attach: function (context, settings) {
try{
if(settings.testModule.tear_just_added){
this.doitnow();
}
} catch(ex){}
}
};
})(jQuery);
js/testModule.overlay.behaviors.js
:(function ($) {
// Disable overlay for creating the "tear" node.
Drupal.behaviors.testModule = {
attach: function (context, settings) {
var $tear_link = $('a[href*="node/add/tear"]'),
tear_link_href = $tear_link.attr('href');
if( $tear_link.length > 0 ) {
// we want to avoid opening the content adding for "tear" content type in the overlay
// so we open it in the current window
$tear_link.unbind();
$tear_link.click(function(e){
window.open(tear_link_href,'_self',false);
e.stopPropagation();
})
}
};
}
})(jQuery);
如果有什么不清楚的地方问一下.
Ask if something isn't quite clear.
