本文介绍了在特定内容类型的
节点创建时执行JavaScript的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我只想在一个特定内容类型的节点创建和节点编辑上执行一个JavaScript函数。这只是一个小功能调用。
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.
我们来调用Drupal 7内容类型
Let's call the Drupal 7 content type "tear", and the JavaScript function "doitnow();"
任何想法如何做？
非常感谢。

推荐答案
您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，准备好了在节点创建/更新后，您必须使用临时会话变量，因为这样可以检查hook_node_view中该变量的存在，并添加告知新的撕裂内容的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.
您必须将此模块放到 sites / all / modules / testModule 目录
You have to put this module to the sites/all/modules/testModule directory.
确定，以下是该模块的代码：
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 ：
testModule.module:
/**
* Implements hook_node_insert()
*
* @see api.drupal/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 api.drupal/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 api.drupal/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
js/testModule.behaviors.js:
(function ($) {
Drupal.behaviors.testModule = {
doitnow: function(){
alert("A new \"tear\" content has just been added!");
},
attach: function (context, settings) {
try{
if(settings.testModule.tear_just_added){
this.doitnow();
}
} catch(ex){}
}
};
})(jQuery);
js / testModule.overlay.behaviors.js ：
js/testModule.overlay.behaviors.js:
(function ($) {
// 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);
询问是否有些不清楚。
